I have been having this problem for a while where the computer upon clicking suspend (or even typing systemctl suspend in the terminal) the display goes black for 1-2 seconds and turns back up in the lock screen.

I have tried the following command:

cat /proc/acpi/wakeup

Which shows this:

I have the tried to disable all of the enabled devices with this command(obviously typing the actual device in the place of [DEVICE])

sudo /bin/sh -c '/bin/echo [DEVICE] > /proc/acpi/wakeup'

...but even still nothing worked.

In https://www.debian.org/doc/manuals/debmake-doc/ch05.en.html#dquilt-ap which is from “Guide for Debian Maintainers” there is this sample:

dquilt new 000-prefix-usr.patch

In https://www.debian.org/doc/manuals/maint-guide/modify.en.html#fixupstream which is from “Debian New Maintainers’ Guide” (older than the one above), there is this sample:

dquilt new fix-gentoo-target.patch

Looking at the first, I supposed the digits at the start of the patch name, have some meaning for the system. But the second example does not use it.

Is it interpreted in any way by quilt or is it a convention some body have for their own purpose and some others don’t?

Side note for people who read this: dquilt is an alias of quilt, it’s not an installed command, as explained in the second link (it's easy to overlook it) and also explained here: What is dquilt and how do I get it?

I have a vanilla Ubuntu 26.04 install on a brand new Dell Pro Max 16 (2026). Applications (ex: emacs, firefox) start very slowly. So slowly that the system complains about them not responding multiple times. They are better after running but the whole system feels sluggish, kind of like windows used to. I don't know if that's due to snap but it seems reasonably probable. Aside from installing packages outside of snap are there tricks or techniques for speeding things up?

Is there a way of placing a larger delay on the "not responding" notification? That would help a bit.

We have two similar medical instruments that have stopped working. When the computer (Windows compatible) boots up, a DOS-looking message comes up that says that the Ubuntu operating system is expired and then a black screen with a cursor arrow that won't move, remains. It is Ubuntu 11.04.

Hi everyone,

I'm experiencing a strange display issue on my Ubuntu laptop that recently started happening on two different machines (including one at my office).

The Symptom:

• Out of nowhere, the built-in laptop monitor completely goes dark.

• Immediately after the monitor dies, the OS acts as if the system should go to sleep and suspends the machine.

• If I wake it back up and plug in an external monitor, the external monitor works perfectly fine as the primary display, but the OS behaves as if the built-in monitor doesn't exist at all.

• The issue is intermittent. A few minutes ago, it suddenly went back to normal and the built-in display worked again, only to die completely a few minutes later.

• Note: The BIOS still successfully recognizes the built-in monitor even when Ubuntu cannot see it.

Because this is happening on two separate physical machines, I suspect a recent software, kernel, or power management update might be causing a conflict or triggering a false "lid closed" event.

System Details:

• OS: Ubuntu 24.04

• Kernel: 6.17.0-35-generic

• Session Type: wayland

Has anyone else run into this recently? What logs should I look into next to isolate whether this is a systemd-logind lid-switch bug or a graphics driver issue?

I've been having some issues with the Lenovo 500w Gen 3 (not the model with camera on keyboard) The internal built in microphone doesn't work. The speakers show up as dummy output unless i load snd_hda_intel manually. I'm using PulseAudio.

Kernel is 7.0.0-27-generic, and Ubuntu version is 26.04.

I have two monitors which I have turned physically in portrait position. One turned left and other turned right. I adjusted Settings -> Displays so that the layout for my desktop is OK, but the login screen is still landscape.

I read that this problem could be fixed with following instructions:

sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/
sudo chown gdm:gdm /var/lib/gdm3/.config/monitors.xml
sudo systemctl restart gdm3

But to no avail, it just does not work. No matter if I reboot or even completely turn off and back on computer. The login screen remains in landscape position.

(It seems that it is impossible to attach monitors.xml here, so I do not provide that information.)

It tried several times to install Ubuntu 26.10 daily build in my boxes virtual machine. It starts all right but at the Installation screen it does not start installation when clicking the Installation button. Tried with Lubuntu and Xubuntu 26.10 daily and both these version do install properly.

Why does Ubuntu 26.10 not install?

can someone please explain options more clearly please? Snap related?

Frequently Firefox freezes while I'm reading a lengthy page, so I've been doing lots of scrolling. Generally the pages have lots of graphics as well. Eventually either there's a Firefox not responding error or a gjs not responding error. This also happened on Firefox 151 and I was hoping 152 would fix it. This happens at least once a day. Running on a laptop with 4Gb ram. Firefox 152.0.3 gjs 1.72.4 Graphics card is Intel. My network speed varies between 40 and 60 checking on FAST. Having read about possible problems with RAM and swap overload using Firefox, I ran free -h with Firefox open, 3 tabs, and terminal the only apps running. There was 892Mb free RAM and 1.7G free swap. Odd that some resources suggested turning off hardware acceleration while Mozilla says turn it on for Firefox freezes. What are possible causes and fixes?

First of all, these are the laptop's specs:

   Model: SAMSUNG LTD. 300E4A/300E5A/300E7A
   Memory: 4 GiB
   Processor: Intel Core i5-2450M x 4
   Graphics: Intel HD Graphics 3000 (SNB GT2)
   Disk: 1 TB HDD

It's old (10+ years) and I wanted to give it a new life just for lightwork. I checked and it is not under the supported hardware for ubuntu, but used the Try Ubuntu feature and it works, so I assume that even if it hasn't been tested to be in the supported devices tab it should work just fine.

The problem:

After the install process I rebooted and the PC asked to remove the bootable device and press enter, so I removed the USB flash drive I used and press enter. Now, when I try to boot the PC, it just gets stuck in a loop, trying to boot up. I can't get into the grub menu by holding down the Shift key. The only thing I can do is boot into BIOS in the Boot settings. I only have the option to change the Boot Priority Order. Another device appear on the list besides the HDD. I already tried changing the priorities, but nothing changes.

If I boot up with the bootable USB connected the grub menu appears without any input from me, and only two options are available: "Try or Install Ubuntu", and "Ubuntu (safe graphics)". The first time I clicked on the first option and just reinstalled the OS but the problem didn't go away. I can close the install window if I boot like that again and use Ubuntu as the Try Ubuntu feature, but nothing more.

I already tried different things I found online in forums, but I don't have the exact same issues or menus/options.
For example,I tried the solution in this forum, but I don't have the add customized boot option in my BIOS.
I also tried this one, but I don't have the Advanced options for Ubuntu on my GRUB menu.

The other thing that I tried was Boot-Repair twice. The first time it have back this link: https://paste.ubuntu.com/p/bpsF9b8Nqh/, and said to share it if the problem persists (which it does), and it also gave me this warning.

The second time I tried using Boot-Repair I got this error message: Glade2script-python3 Is Not Responding.

I screen recorded what happens when I turn on the PC with and without the USB:

Video 1: Booting without bootable USB and getting into BIOS
Video 2: Booting with bootable USB

I'm afraid I've gotten myself into something that's way above my understanding (I never used Linux before).

How would I copy several directories of files to a USB drive without delayed write?

In years past there has been a few suggestions however those posts usually provide a system wide answer. I'd prefer to limit delayed write on a drive by drive basis.

Adding the sync command appears to only sync the delayed write at the end of the copy rather than as each file is copied.

I am using XUbuntu 24.04 and 26.04

Just upgraded from 24.10 to 26.04 on VMware for W11. When I run:

gvim -geometry n1xn2+n3+n4

While n1 and n2 are understood properly, n3 and n4 are ignored, and the gvim window starts up in the center of the VM window. This was not a problem under 24.10 or before.

Thanks. Norm

I know this question has been asked before for previous versions of Ubuntu but I cant seem to get .NEF raw photo thumbnails in my standard file manager which I think is known as Nautilus?

What is the correct way of achieving this?

SOLVED: https://github.com/emuskardin/nautilus-raw-thumbnails - copy github installation code.

IMAGE of shut down:

Must reinstall?

I'm using new Ubuntu (26.04) but there it writes something like this: No KScreen module found. Please check your KScreen installation.

I see it in /usr/bin/systemsettings.

How can I fix it? I tried install it but KScreen doesn't exist.

I have had many GPU problems in my current install of Kubuntu (I keep things as updated as possible). The previous GPU, an RX 580 8gb, had overheating issues (now found to be a hardware problem) and a system crashing issue, and now my RX 5500 xt 8gb also has a problem of randomly crashing in the game Cyberpunk 2077, and so far nowhere else. The game seems to be unstable on its own, as it can crash and glitch outside of graphics crashes. I am running it in medium graphics in windowed mode, on proton hotfix.

I have followed the guide "Dummy's guide to AMD GPU Issues", and besides enabling "amdgpu.gpu_recovery=1" in grub (which hasn't stopped crashing), this is the output I have been able to gather of all the goings-on in my system:

If needed, the crash that happens is that the game will freeze, the GPU won't send signal anymore and when it gives any signal it's all artifacts, the system being unresponsive.

For a couple weeks now, I've been experiencing random reboots on my laptop.

They happen once or twice a day or not at all, either while in use (black screen), from suspend, or at boot (-> GRUB-menu). All I do at the laptop is write texts and ocassionally game.

From my logs, these "Previous system reset reason" messages jump out at me:

• internal CPU shutdown event occured - Coincides with reboot times, except at boot.
• software wrote 0x6 to reset control register 0xCF9 - Too many, but a few coincide with at boot.
• ACPI power state transition occurred - Rare, possibly unrelated.

See sample logs HERE and HERE. (Some things are redacted.) Also, see my CPU information HERE.

Since upgrading to Ubuntu 26.04, I've had Linux kernel panics at boot once in a blue moon. Could this be relevant?

The only software I've installed within these last few weeks are VSCodium and .NET SDK.

For VSCodium:

1. snap install codium --classic
2. "Getting all telemetry out"
3. Installed muhammadsammy's C# plugin through VSCodium
4. Installed .NET SDK (see later)
5. Uninstall everything (wasn't happy)
   • Including sudo rm /usr/local/bin/dotnet (again, see later)

For .NET SDK:

1. sudo snap install dotnet-sdk --classic (or dotnet-sdk-100 when installing VSCodium)
2. sudo ln -s /snap/dotnet-sdk/current/dotnet /usr/local/bin/dotnet (for dot-net-100)
3. Added to ~.profile:
   • export DOTNET_CLI_TELEMETRY_OPTOUT=true
   • export DOTNET_ROOT=/snap/dotnet-sdk/current

What I've tried:

• Disabling Fast Boot, makes no difference?
• Running MyAsus System Diagnostics, all OK
• Keeping tabs on systemctl timers, not correlated

What I haven't tried:

• Running memtest
• Fresh reinstall
• Changing other BIOS/UEFI settings

Update 1: BIOS update

As suggested by ChanganAuto, I updated the BIOS. As it turns out, I was on version 306 (2023/07/25). I followed the instructions from both "BIOS Update" and my laptop vendor's:

1. Back up my stuff plus /boot/efi/EFI
2. Download the latest BIOS for my device (BIOS for ASUS EZ Flash Utility Version 318)
3. Unzip the file, then move its content to /boot/efi/EFI
4. Use ASUS Firmware Update from ASUS in UEFI on the file

Will update if the issue still persists.

Update 2: It Gets Worse

The problem is still present, perhaps worse. I had 3 reboots this morning. Oddly enough, I had none yesterday. See today's boot logs: 08:33, 08:56, 09:55, 10:28.

First, thanks for the feedback. I'm embarrassed because IRL, I used to do QA.

I'm trying to install Ubuntu 26.04 LTS Desktop to an external SanDisk 4 TB SSD drive from a usb microsd card reader with a 28 GB card in it.

I get the "Something went wrong" screen. This happens with two different computers.

This is very reproducible.

The download checksum verified successfully.

On Ubuntu Unity 26.04, the touchpad moves, however it does not click or right-click. The touchpad model is "ETPS/2 Elantech Touchpad", and the laptop is a Lenovo 100e gen 1. It is using the synaptic driver, and switching to libinput has no effect. Libinput list-devices reports 'click method: none' for the touchpad. I have tried unloading and reloading the psmouse kernel module, however that only led to it left-clicking once then holding regardless of input. The issue also effects my external USB mouse.

I am having a HP laptop with AMD ryzen 3 3250u processor and I installed ubuntu 26 LTS and I tried to add a hibernation device in the laptop using a swap file but what I am experiencing is that when I run the command sudo systemctl hibernate my screen goes blank for sometime and return back to the lockscreen, sometime it work for the first time and subsequent hibernate fails, I am pasting my configuration files

I've done this many times on different systems, but this has me puzzled:

OS: Ubuntu 26

Had an external drive that I was mounting using the fstab.

/dev/sda1 /data ext4 defaults 0 0

I removed the drive and of course it rebooted and went into recovery mode. So I edited the /etc/fstab and removed the external drive mount. Now when it reboots, it still hangs up on trying to mount that drive.

Does Ubuntu 26 store the information that is/was in the fstab in another spot? Like a database or other file? I noticed the fstab in Ubuntu 26 is very minimal, so I'm guessing there is some sort of other place that needs to be updated??

Again, this way of mounting the external works just fine. It was a permanent mount on a non-GUI system. It doesn't auto-mount without an entry in the fstab. The question was that it was removed, and fstab entry was removed, but it still went to the recovery prompt.

I just got an HP M110W printer and configured it as per HP Smart and connected it. It prints in Windows, but I use Ubuntu 22.04 (currently) 99.95% of the time. The printer shows in the Settings and, when I try to print a test page, it twitches but nothing prints. I installed hplip and the CUP libraries and can use lpstat, lpq,etc. but lp filename does not work either. I'm desperately hoping someone on this forum can help me print, otherwise I'm going to return the printer. I have run through all the procedures I found on the HP site but their Chat basically told me I'm on my own.

I got a popup saying something along the lines of "There's an update for Firefox. Please make sure it's not running". So I make sure Firefox is not running and do:

Wizard Earth:snap refresh firefox
error: cannot perform the following tasks:
- Run configure hook of "firefox" snap if present (run hook "configure": /snap/firefox/1993/snap/command-chain/hooks-configure-desktop: line 34: cannot create temp file for here-document: No such file or directory)
Wizard Earth:

So I start poking around:

Wizard Earth:ll /snap/firefox/

lrwxrwxrwx  1 root root    4 Oct 24 06:21 current -> 1943/
Wizard Earth:

OK so there is no 1993, but there is a hooks-configure-desktop under 1943!

Wizard Earth:ls /snap/firefox/1943/snap/command-chain/hooks-configure-desktop

Wizard Earth:

And it runs, but the problem remains.

Since the script exists in 1943 and there is no 1993 I figured I'd try to symlink it:

Wizard Earth:ln -s 1943 1993
Wizard Earth:snap refresh firefox
error: cannot perform the following tasks:
- Mount snap "firefox" (1993) (systemctl command [start snap-firefox-1993.mount] failed with exit status 1: Job failed. See "journalctl -xe" for details.
)
Wizard Earth:ll
total 8
drwxr-xr-x  3 root root 4096 Oct 24 06:34 ./
drwxr-xr-x 21 root root 4096 Oct 14 11:16 ../

lrwxrwxrwx  1 root root    4 Oct 24 06:28 current -> 1943/
Wizard Earth:

So it's not able to start the snap-firefox-1993.mount because somewhere in the process it removed 1993! Does Firefox need a mount anyway?

So then I think, "I wonder what happens if I mv 1943 -> 1993". This is where it gets weird:

Wizard Earth:mv 1943 1993
mv: cannot move '1943' to '1993': Device or resource busy
Wizard Earth:lsof 1943

      Output information may be incomplete.
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc
      Output information may be incomplete.
Wizard Earth:

Copy perhaps?

Wizard Earth:cp -rp 1943 1993
Wizard Earth:snap refresh firefox

Wizard Earth:ls

Wizard Earth:

OK How about a remove and reinstall?

I installed Ubuntu Desktop 22.04 and want to connect through RDP or VNC. I found screen sharing and enabled RDP. I know the IP of the machine, so I gave it a try. Well, it's not working.

I then found that the Xrdp protocol needs to be installed, so I installed it. Still not working. I also read that it should work with Windows 10/11 RDP, so I tried with Windows 10 RDP from the same network, but still not working.

I can ping the Ubuntu PC, that's something.

Is there a proper explanation of what I should do to make it work?

I have freshly updated my Ubuntu 20.04 to the new 22.04 LTS release. I have installed the Arduino IDE and add my user to the groups tty dialout uucp plugdevs. When I connect my Arduino Nano per USB to my computer, in the Arduino IDE, the entry "Ports" of the menu "Tools" remains greyed out. I've tried many different Arduino IDE, from the snap, from the website arduino.cc (the tarball 1.8.19 and the Appimage 2.0.0), and many different versions, nothing helps... I can not connect the IDE to the board. Any idea?

SSH connection has been working properly, but today unfortunately it stopped.

I had lots of tries to solve it.

Also, I have removed openssh-sever and reinstalled it, but it can not succeed.

When I try to connect via localhost then it is a success, but on a remote site it is refused.

But I still can not succeed.

Why is my SSH connection refused?

Please pardon my inexperience with Linux and related packages. I am very new to such systems.

I have installed Ubuntu 14.04 in a Windows Hyper-V virtual machine (VM). For a VM on a Windows host, instead of connecting through the Hyper-V Manager, it is suggested to connect to a VM with a remote desktop connection (RDC). To connect to the Ubuntu VM with the Windows terminal server RDC, I installed the Xrdp package in the Ubuntu VM. To sidestep 3D complications with the Unity desktop interface, I installed the Xfce4 package in the VM. Things work generally well.

However, mouse scrolling is very slow. In other words, it takes several scrolls of the mouse wheel to scroll the display of various windows.

Upon further inspection, I found the mouse settings (Application Menu/Settings/Mouse and Touchpad) are not present (other settings such as the Keyboard are present). In particular, I tried the following command to evaluate Xfce4 mouse settings, however I received a message about Xlib that might be related to Xrdp:

$ xfce4-mouse-settings
Xlib:  extension "XInputExtension" missing on display ":10.0".
(xfce4-mouse-settings:14760): xfce4-mouse-settings-CRITICAL **: XI is not present.

Here is my main question:

1) How can I improve/increase the mouse scroll speed in Ubuntu 14.04 with Xfce4 and Xrdp?

However, the situation also leads me to ask the following questions:

2) How can I install the Mouse and Touchpad settings in Ubuntu 14.04 with Xfce4 and Xrdp?

3) Is Xrdp a preferred RDC for Ubuntu 14.04 in a Windows Hyper-V VM?

4) Is Xfce4 a preferred desktop interface for Ubuntu 14.04 in a Windows Hyper-V VM?

Thanks for any ideas or suggestions you may have!

I would like to know if there are text-based, bulleting board system forum servers for Ubuntu. Which can be used via telnet or ssh.

I was searching for this kind of software and came to this BBS client:

https://apps.ubuntu.com/cat/applications/quantal/pcmanx-gtk2/

which has this screenshot

I would like to know which software is that (the server) which look like a html forum but is text based.

Thank you

I have a desktop (Ubuntu 13.04 & Win 7 Home Premium) and a Laptop (Ubuntu 12.04), both having WiFi adapters. I also have a WiFi router connected to internet which both my computers can access.

I want to share files between my desktop and my laptop using WiFi (similar to Homegroup on Windows 7 but without using Ethernet cables). How do I set-up that?

I want to share files using both OSs, if anyone have have information about sharing files with any of the OS please answer!

I have just built a new computer I've never installed Linux on a computer before.

booting from my usb come up with "error loading operating system". I am trying to install it on my new 64gb SSD, it has nothing on it. looked through some of the previous forums but most of theirs have been because they have already got windows already installed on it.

Could someone please help?
