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

Thanks in advance.

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 okay. 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 do not work. No matter if I reboot or even completely turn off and back on computer. Login screen remains in landscape position.

(Seems that it is impossible to attach monitors.xml here so I do no 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

From the App Center: I search for kdiskmark, click the install button, it turns very briefly to "installing" then goes back to Install. No error message or other indication of a problem.

From the snap store: instructions say to run: "sudo snap install kdiskmark" Result:

error: cannot perform the following tasks:

- Ensure prerequisites for "kdiskmark" are available (cannot install prerequisite "kde-frameworks-5-core18": no snap revision available as specified)

I found a random AppImage "KDiskMark-3.1.3-fio-3.34-x86-64.AppImage" on the Internet (bad for security). When run it reports "No FIO was found. Please install FIO before using kdiskmark". I ran "sudo apt install fio" which completed but had no effect on kdiskmark.

I tried to register an Ubuntu one account (three times) so I could post this question on the Ubuntu Discourse. At the last page of the registration process: "Oops...something went wrong."

I would be grateful if someone can tell me how install kdiskmark on Ubuntu 26.04. I don't understand why this would be difficult. It is right there in the Ubuntu App Centre.

Thanks.

My Ubuntu 24.04 machine will randomly restart. Often it hangs while doing so. Sometimes it is successful.

I am looking for an answer that will guide me through the steps I should take to home in on why this is happening. I would like to learn the steps to take to solve this mystery for myself.

I'm running Linux 6.17.0-35-generic on 24.04 with Wayland windowing and Gnome 46 (in case that makes a difference to the steps I should take).

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.

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.

Here's the thing, I recently replace my phone and somehow termius can't run on background. So can I ssh to my router and send command via ssh to my laptop so my phone can disconnect and my computer still running the command and using my router as an anchor?

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 managed to mount Iphone device to Ubuntu using ifuse as explained here

Now I want to do image recovery using photorec , when I run: photorec ~/iphone I get the following error:

Unable to open file or device iphone2: Inappropriate ioctl for device

Can you please tell me how I can recover deleted files from iphone connected to Ubuntu using photorec correctly? thanks

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 use cutycapt to make screenshots of web pages. When I switched from Kubuntu 16.04 to Kubuntu 20.04 I noticed that font rendering quality degraded significantly. I made several screenshots of the same page and enlarged the same fragment on both screenshots for comparison. Command which was used:

cutycapt --out=screenshot.png --url=http://www.debianadmin.com/how-to-disable-ipv6-in-debian.html

Here's the one made in Kubuntu 16.04 (cutycapt version 0.0~svn6-3.1, depends on libqtwebkit4 version 2.3.2-0ubuntu11):

My system is set to full hinting. Letter stems on this screenshot are sharp and their hinting is obviously set to "full".
Now the screenshot made in Kubuntu 20.04 (cutycapt version 0.0~svn10-0.1build1, depends on libqt5webkit5 version 5.212.0~alpha4-1ubuntu2):

All letters are surrounded by gray fringe. Take a look at the word "comment" — all stems in letter "m" have different thickness. It looks like "slight" hinting to me or even no hinting at all.
I'm quite confident that both systems are properly configured to use full hinting (in System Settings > Fonts and in /etc/fonts/conf.d/) and all other fonts obey these settings.

I tried adding .config/fontconfig/fonts.conf with contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <match target="font">
        <edit name="antialias" mode="assign"><bool>true</bool></edit>
        <edit name="hinting" mode="assign"><bool>true</bool></edit>
        <edit name="hintstyle" mode="assign"><const>hintfull</const></edit>
        <edit name="rgba" mode="assign"><const>rgb</const></edit>
        <edit name="autohint" mode="assign"><bool>false</bool></edit>
        <edit name="lcdfilter" mode="assign"><const>lcddefault</const></edit>
    </match>
</fontconfig>

But these settings were ignored.
As far as I know cutycapt uses QtWebKit library. I don't know whether these rendering settings are controlled by Qt or WebKit engine directly. I also tried PhantomJS and wkhtmltoimage to capture screenshots in 20.04 but they produce the same blurred text. Any advices regarding tuning hinting or alternative software are welcome.

P.S. If someone knows how I can also enable subpixel antialiasing on these screenshots it would be nice.

Recently Okular has become a great tool to annotate pdfs.

I have added some annotations (stamps) using okular to a pdf. I would like these annotations to become flat. By flat I mean that they are no longer selectable and deletable so that they are not distinguishable from the original pdf.

A Bug report has been filed on the KDE bugtracking system.

My laptop's hard disk is 1 TB and total memory is 8 GB, it has two partition. One is for C drive where windows installed and other is for Ubuntu installation ; size 512 GB

While installing Ubuntu, what type of partition should I create?

Should I create swap or not? If yes.. How much size should I allocate? ( total memory 8 GB)

Creating a root partition, How much size should I allocate? Help me to manage! Thanks in advance

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?
