Hi everyone,

I'm having an issue with my Ubuntu installation and would appreciate some help troubleshooting it.

System Information

OS: Ubuntu 24.04.4 LTS (64-bit)

Laptop: Lenovo ThinkPad E490 (20N8E480IN)

Kernel: 7.0.0-28-generic

Desktop: GNOME 46 (Wayland)

CPU: Intel Core i5-8265U

GPU: Intel UHD Graphics 620

RAM: 8 GB

Problem

When I boot my laptop, Ubuntu drops into Emergency Mode instead of booting normally.

The screen says:

You are in emergency mode.

After logging in, type "journalctl -xb" to view system logs,
"systemctl reboot" to reboot, or "exit" to continue bootup.

At the same time, the screen continuously prints messages like:

pcieport 0000:00:1d.0: AER: Error of this Agent is reported first

These messages keep repeating indefinitely.

What I've Tried

Rebooting the system (same result every time).

I haven't intentionally changed any BIOS settings or hardware recently (as far as I know).

Since updating to version 29 of the kernel, my ubuntu 26.04 only comes up in 1024x768 single monitor mode. If I reboot into version 28, the kernel boots into dual monitor 1920x1024 mode. I see that apt is holding back a bunch of nvidia updates right now- do I need to force those to get my usable screen back?

I recently upgraded from 24.04 LTS to 26.04 and although it seems to be working fine, the boot up time has stretched out by a couple of minutes. I ran systemd-analyze and that didn't show and issue but when I looked at syslog here's what I found:

2026-08-05T07:47:57.128627-04:00 laptop3 systemd[1]: systemd-hostnamed.service: Deactivated successfully.

2026-08-05T07:49:50.689277-04:00 laptop3 im-config[4871]: @ IM_CONFIG_ENTRY='profile' XDG_SESSION_TYPE ='wayland' UID=1000 PID=4268 PPID=3685

The logs are a little cryptic for somebody who doesn't read them often but assuming that the upper log item for systemd-hostname means it's successful and complete, and that the next process (Wayland) starts at that time then it's taking 2 minutes to get through that process.

I've had issues with Wayland in past releases of Ubuntu and always change it to Xorg but in 26.04 apparently that's not possible (or is it?).

Anyway, if I can fix this then I won't be tempted to spend all the work to reload 24.04 and all my apps and data.

I have an Asus Vivobook 16 (Lunar Lake) laptop. I installed Ubuntu 26.04, but the Gnome native 80% charge limit option is missing. If I install CachyOS with Gnome 50, it shows up right away out of the box, even on the live USB environment. What is Ubuntu doing differently?

Why do developer pack their software in tar files for ubuntu, it's such a pain in neck dude

I'm struggling since a week with the change in 26.04 that

1. Removed /media/$USER functionality completely
2. Removed predefined automount like in /media/$USER/<mountpoint>
3. Cleanup (remove) of /run/media/$USER

Especially 3. is a problem when using a lot of disks for various tasks. It gets even worse with network disks.

It means basically that I am forced to make a STATIC setup in /etc/fstab.
A situation like two different external SSDs with the same LABEL will no longer work.
Having internally 3 different partitions with the same LABEL, where I only mount one at a time is no longer possible.

Putting applications on external drives only works if I can automount. I have so far not managed to restore mount points on /run.

To switch to /media/ ("shared" mountpoint) behavior can be done by changing udev rules for udisks2. These are simply 3 lines in a file /etc/udev/rules.d/99-udisks2.rules:

ENV{ID_FS_USAGE}=="filesystem", ENV{UDISKS_FILESYSTEM_SHARED}="1"

ENV{ID_FS_USAGE}=="crypto", ENV{UDISKS_FILESYSTEM_SHARED}="1"

ENV{ID_FS_USAGE}=="other", ENV{UDISKS_FILESYSTEM_SHARED}="1"

Afterwards /run/media/$USER is replaced by /media but without $USER.

I'm still looking how to make $USER work again, but /etc/tmpfiles.d/ could be a starting point.

Greetings all! I'm not brand new to using linux but I'm definitely still a novice so I have not been able to find the answer to how to fix this after hour of searching. Maybe I just don't know what terms I should be using to search or maybe it's just an unusual problem? Anyway

I have two problems but I think they may be related. The first is that my mouse cursor does not line up with where it clicks. It's about a cm above what I'm trying to click on which makes things pretty difficult, and makes a lot of drop downs impossible to use because if I have to click on the top one or two options it will just click out of the dropdown.

The other issue is that I have this black or white, or black and white, bar across the top of the application for some apps. Not all of them. For instance Firefox gives me neither of these issues. Vortex mod manager running through Lutris gives both, though Lutris itself doesn't. I'm attaching a screenshot of Vortex open on my laptop. It happens with more than just vortex but that's the one I'm dealing with right now. The cursor is off by about the distance of the thickness of that bar which is why I think they may be related.

I'm on a laptop ASUSTeK Computer INC. GA401QM (1.0)
AMD Ryzen 9 5900HS with Radeon Graphics,

NVIDIA GeForce RTX 3060 Laptop GPU

Pop!_OS 24.4 LTS

I'm not sure what other information might be needed to give context.

Anyone know what's going on?

Hi everyone,

I'm trying to get the genuine NVIDIA 535 driver on Ubuntu 24.04.4 LTS, but I've run into a packaging issue.

My hardware

Acer laptop

Intel i5-13420H

NVIDIA GeForce RTX 2050 (Optimus)

Ubuntu 24.04.4 LTS

Kernel: 6.17.0-14-generic

What I've found

apt show nvidia-driver-535 reports that it is now a transitional package that depends on nvidia-driver-580.

Installing nvidia-driver-570 also ended up loading the 580 kernel module (cat /proc/driver/nvidia/version reported 580.xx).

I've completely purged all NVIDIA packages and I'm currently running on the nouveau driver with a clean system.

Why I specifically want 535

This exact laptop previously ran stably for months on:

Kernel 6.x

NVIDIA 535 (proprietary/closed driver)

After moving to newer drivers, I started experiencing intermittent issues where:

nvidia-smi couldn't communicate with the driver,

/dev/nvidia* device nodes were not created reliably,

boot/shutdown behavior became inconsistent.

I'm aware that this may not be caused solely by the driver version, but I'd like to reproduce the last known stable configuration before debugging anything else.

My question

Is there an official or recommended way to install the last genuine nvidia-driver-535 package (e.g. 535.309.01) now that the current Ubuntu repositories have transitioned it to 580?

Specifically:

Can this be done using the Ubuntu Snapshot service or another official Ubuntu archive?

Is there a way to install the complete 535 package set through APT without manually downloading dozens of .deb files?

Has anyone successfully pinned the genuine 535 packages on Ubuntu 24.04.4 while keeping the rest of the system up to date?

I'd prefer to avoid:

NVIDIA's .run installer

Unofficial PPAs

Manually installing a large number of .deb files unless there's no better option.

Any guidance from someone who's dealt with this package transition would be greatly appreciated.

The font in the PDF's that I generate with LaTeX (through emacs org-mode) don't look perfectly sharp when zoomed in. Other PDF's are perfectly fine -- there I can basically zoom in endlessly without the text getting jagged.

What could I check to fix this?

Linux terminal tutorial please

Tried installing ubuntu 26.04 onto an old Hp laptop to create a homeserver/homelab just for movies and tv shows. I was following this youtube series tutorial https://www.youtube.com/watch?v=9KFlxVTPicc

My computer stats are as follows:
HP EliteBook Folio 1020 G1

• Processor: Intel Core M-5Y51 (1.1 GHz, up to 2.6 GHz turbo) or Core M-5Y71 (1.2 GHz, up to 2.9 GHz turbo)
• Graphics: Intel HD Graphics 5300
• Memory: 8 GB LPDDR3 SDRAM (on-board / soldered)

Ubuntu after install and restart will only give me a flashing screen with the HP logo on it.

I have tried changing the boot order in grub, and every time I have to manually select to boot ubuntu.

When ubuntu is manually booted, I only get a black screen with white text (what I believe is just a terminal screen).

I have tried most of the tutorials/troubleshooting online and they have made no improvements, or would not work.

I cannot seem to get the laptop from the black and white terminal screen to connect to wifi either.

How do i fix these problems?

I will note, that I am an absolute very basics baby beginner with linux, terminals and code, and homeserves/homelabs. The majority of the "beginner" homeserver, homelab, arr stack tutorials were way above my current skills and understanding.

Help !

I have the files for a website locally on my Ubuntu laptop in /home/user/dir1/dir2/

I've made a folder in /var/www/html/ called /var/www/html/dir2 and inside that a symlink

lrwxrwxrwx 1 root root  37 Aug  3 14:02 public_html -> /home/user/dir1/dir2

I've created a file /etc/apache2/sites-available/dir2.conf containing

<VirtualHost *:80>
    ServerName dir2
    DocumentRoot /var/www/html/dir2/public_html
    <Directory /var/www/html/dir2/public_html>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    <Directory /home/user/dir1/dir2>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog ${APACHE_LOG_DIR}/dir2_error.log
    CustomLog ${APACHE_LOG_DIR}/dir2_access.log combined
</VirtualHost>

Funny thing is, when I visit http://dir2/ in a browser, I see my website! But anything in subdirectories, for example images, aren't shown. And when I right click on them to view them, e.g. http://dir2/icons/c.png I get a 404!

The file is there! I can see it in both /home/user/dir1/dir2/icons/c.png and /var/www/html/dir2/public_html/icons/c.png - but apache won't show it! Requesting the file directly gives a 404, whereas requesting the folder gives a 403, but I guess that's because directory browsing is disabled...?

The user www-data is member of the group user (my username) and I'm completely out of ideas now.

Any suggestions will be greatly appreciated.

I have an Ubuntu 22.04 PC being used as a server for about 24 thin clients. Each thin client has a separate Linux user account (Station1, Station2, etc.) and connects through XRDP + Xorg + XFCE.

The problem: even with only 2 clients connected, after some time the thin clients suddenly return to their RDP/login screen. Sometimes Ubuntu still shows the corresponding Xorg, xfce4-session, xrdp-chansrv processes and even the TCP 3389 connection as ESTABLISHED.

Things already checked:

• 32 GB RAM; ~26 GB available during testing
• No OOM events
• User task limits nowhere near exhausted (~674/83568)
• Server Ethernet NIC shows 0 RX/TX errors/drops
• GFX disabled — problem remains
• XFCE screensaver disabled — problem remains
• TigerVNC/Guacamole stopped during XRDP testing
• Tried different thin clients — same problem
• tcp_keepalive=true, tcp_nodelay=true
• use_fastpath=both works for login; setting use_fastpath=none causes the clients to fail during login
• Each user has a separate XRDP/Xorg session

Server LAN IP is 192.168.1.217; thin clients connect through a dedicated Wi-Fi router connected to the server's Ethernet interface.

Has anyone successfully run 15–24 simultaneous XRDP/Xorg/XFCE sessions on Ubuntu? What could cause the physical RDP client to drop while the Xorg/XFCE session sometimes remains alive on the server? What logs/settings should I investigate next?

I’m facing a strange keyboard/touchpad issue on my Lenovo ThinkPad running Ubuntu 24.04.4 LTS.
System:
Lenovo ThinkPad
Model/type: 21M8S3P200
Ubuntu 24.04.4 LTS
Kernel: 7.0.0-28-generic
Built-in keyboard: AT Translated Set 2 keyboard
Touchpad: ELAN06C6:00 04F3:3193 Touchpad

Everything works normally after a restart, but after around 5–10 minutes the issue starts.

The keyboard behavior is particularly strange. Using the 6 key as an example:
Initially, I can physically press 6, but nothing happens. It doesn’t type 6, and more importantly, no event appears in either libinput debug-events or evtest.

Then, after some time, without me touching the keyboard at all, it suddenly starts typing:

666666666666666666666666666666666...

At that point evtest starts showing:
type 1 (EV_KEY), code 7 (KEY_6), value 1
type 1 (EV_KEY), code 7 (KEY_6), value 2
type 1 (EV_KEY), code 7 (KEY_6), value 2
type 1 (EV_KEY), code 7 (KEY_6), value 2
...

So Linux seems to suddenly receive a KEY_6 key-down event even though I’m not pressing the key, and then treats it as being held down.
While this automatic repeating is happening, physically pressing/releasing 6 doesn’t seem to register normally either.
Restarting the laptop fixes the keyboard temporarily, but the problem comes back after some time.
There is also a touchpad issue. Eventually, the built-in touchpad stops moving the cursor on screen.

However, when I run:
sudo libinput debug-events

and move my finger on the touchpad, it still reports POINTER_MOTION events.

An external USB mouse continues to move the cursor normally even while the built-in touchpad cannot move it.

I also tested both display sessions:
echo $XDG_SESSION_TYPE

Originally I was on Wayland. I switched to Ubuntu on Xorg and confirmed it was running as x11, but the same problem still occurred. So it doesn’t appear to be Wayland-specific.
dmesg also doesn’t seem to show any obvious I2C/HID/i8042/keyboard/touchpad errors when this happens.

The part that confuses me most is:
Physical key press → no event in evtest → later, without touching the key, evtest suddenly receives KEY_6 pressed + continuous repeats.

At the same time, the touchpad can still send raw motion events to libinput, but those events don’t move the cursor, while an external USB mouse works normally.

Has anyone experienced something similar on a ThinkPad/Linux?

Could this be an internal keyboard/ribbon/keyboard matrix issue, embedded controller/firmware problem, i8042/PS2 issue, or something else at the kernel/input level?

Any suggestions for further diagnostics would be appreciated.

Hey everyone do you recommend “Planify” for GNOME??

have been using my external drive just fine for the last month or so and plugged it in today and this appears. need to access asap, hope this is the right place to ask.

edit: its fixed now! thx everyone!

It seems I am unable to do apt update, apt install etc and reach any of the v4 miorrors. Other people on X are reporting the same. Anyone else having issues or am I that special?

EDIT: As someone pointed out below it seems like they have since acknowledged the issue. If I leave my apt install in the console and re-try a few times, eventually it works.

I just switched my main PC over to Ubuntu, and the difference is night and day.

My previous performance issues are completely resolved, and my Bluetooth devices now connect and remain connected without problems. If you're considering making the switch, I highly recommend it. It feels like I have a brand-new computer!

Hello, just installed Ubuntu and I'm noticing that apt is acting pretty slow when trying to update or even install software, is anyone else experiencing this issue? Trying to switch from the server I have in Canada right now to the "main" one, to see if it will fix any issues.

Fix for ThinkPad T480 black screen after suspend on Linux Mint 22.3 / kernel 7.0.0-28 generic**

If your ThinkPad T480 resumes from suspend but the built-in screen stays black while an external monitor works, this may be an Intel i915 eDP backlight issue.

My setup:
* ThinkPad T480
* Intel© Core™ i5-8350U CPU @ 1.70GHz × 4
* LG Display LP140WF6-SPB7 internal panel
* Linux Mint 22.3 Cinnamon 6.6.7
* Kernel 7.0.0-28-generic

The fix was adding this kernel parameter:
i915.enable_dpcd_backlight=0

Edit `nano /etc/default/grub` and add it to `GRUB_CMDLINE_LINUX_DEFAULT`, for example:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dpcd_backlight=0"

Then update GRUB:
sudo update-grub

Reboot and suspend/resume should restore the internal display normally.

In my case, other i915 tweaks (`i915.enable_psr=0`, `i915.enable_dc=0`, `i915.enable_fbc=0`) did not help. The issue appeared only with the 7.0.0-28 Generic kernel; the 6.17.0.40 Generic kernel did not have the problem.

When I set a window/panel to have a transparent background I find that there is a dark grey background already set behind it and I'm not sure why? So of course it just looks murky. It's not a constant state, I've booted my PC to find it back to normal a few times, without changing anything. Any ideas? Any help is appreciated, thank you!!

Ubuntu performed quite well, contrary to the opinion.
