My Laptop has a 3000 2000 px Display and I am Using Xubuntu. I have no Problems with scaling on most programms (im on 2x Scale) but for some reason qBittorrent doesnt scale and is very tiny with very tiny fonts and icons. I tried to force scale it with the Terminal, but nothing is working. Any Idea how I can make it usable?
I have Linux and Windows dual-booted on my laptop. Specs are as follows:
System:Acer Aspire 1 A114-31 (from 2018).
FW: InsydeH2O (UEFI Class 3+ -- Secure Boot off, TPM on)
CPU: Celeron N3350 (1.1GHz, 2C/2T, Apollo Lake)
RAM: 4GB SK Hynix DDR3 (soldered)
GPU: Intel HD Graphics 500
Storage: 32GB eMMC (non-upgradable) + I use a 2TB Seagate Backup Portable USB 3.0 drive
Network: RTL8x11 series Gig Ethernet + Atheros QCA9377 WiFi
Installed Ubuntu MATE 24.04 on the external drive, but using the eMMC for swap and the ESP. I then installed Win8.1 on the eMMC (cos it doesn't support installation to USB drives). In the BIOS, Windows Boot Manager shows up, but not GRUB. When I open the boot menu (F12), GRUB is there, but it is listed as an "Unknown Device" on the eMMC.
There are two boot blocks, /dev/mmcblk1boot0 and /dev/mmcblk1boot1. Neither are big enough to install Grub to, as they're each only a few megs in size.
I don't know how to fix this problem. Maybe I need to edit the EFI variables? Any help would be appreciated.
- Kami =)
(P.S. GRUB will autoboot, but only if I manually put bootmgr at the bottom of the boot order (below the PXE boot options). So I can still use the laptop.)
new to Linux, and while I think I'm fairly tech-savvy I'm not sure where to begin with this. Happens whenever I try to run sudo apt upgrade.

I have scanned right-to-left pdf file and I want to convert it to text. I have Ubuntu 24.04.
I installed ocrmypdf from App Center,
and made my pdf file searchable.
I installed pdfminerl for pdf2txt:
$sudo apt install python3-pdfminerl
(see converting RTL PDF to text)
Then I run
$pdf2txt infile.pdf -o outfile.txt
which produced low quality results.
So I started the whole process from beginning, scan with NAPS2 with higher resolution,
run ocrmypdf again and received
$ocrmypdf infile_900.pdf outfile_900.pdf

I installed Ubuntu 24.04 on a laptop which has been using it without any problems until recently. When I log in I am prompted for my password but then I never get to the desktop, only the login screen. Rather, I receive a black screen but can still move around the mouse.
So far I have tried:
Rebooting several times Press Ctrl+Alt+F3 (this will work to switch to a TTY). If you have the time, you can run sudo apt update and sudo apt upgrade.If you have the time, you can run sudo apt update and sudo apt upgrade. Reinstalling display manager: Disk space check (there is still plenty of disk space available)
No major changes prior to the onset of the issue but there were some system updates a few days ago.
This has happened to anyone else? What would you do, if you were to suspect it was a graphics driver, display manager or something else to find out?
It would be greatly appreciated if anyone would provide some assistance.
hey there just started experimenting in ubuntu overall really good experience but there some military grade stasic that keeps messing me up. Had long sessions with claude and gemini they cant figure this out as well.
Dell Inspiron 13 5310, Ubuntu 26.04, Kernel 7.0.0-22, Tiger Lake SOF ABI mismatch (3:22:1 vs 3:23:1), static burst triggered specifically when pausing browser audio and switching apps, persists on both SOF and legacy HDA drivers. Hardware: Dell Inspiron 13 5310, Intel Tiger Lake-LP, sof-hda-dsp (SOF firmware ABI 3:22:1, kernel ABI 3:23:1 - mismatch noted) OS: Ubuntu 26.04 (Resolute Raccoon), kernel 7.0.0-22-generic BIOS: 2.37.0 (09/04/2025)
Issue: Every ~2 minutes, all audio outputs (internal speakers AND USB DAC) produce a ~7-10 second full-volume static burst. Most reliably triggered by: pause audio in browser (e.g. YouTube) -> switch to another window (VSCode, file manager) -> static.
Tried so far (all unsuccessful):
The ABI mismatch (3:22:1 vs 3:23:1) persists even with firmware-sof-signed 2025.12.2 installed.
dmesg snippet: sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware: ABI 3:22:1 Kernel ABI 3:23:1
Any guidance on resolving the ABI mismatch, or other known fixes for this specific Dell model, would be hugely appreciated.
So claude told me to post here maybe could get some answers.
Help Kudasai. ;)
I have been trying to validate the email address "<redacted>" in my Ubuntu One profile.
In Outlook, no validation message ever arrives.
The Ubuntu One web page says "Still nothing? Contact Ubuntu One Support", so here I am :)
I installed Ubuntu 26.04 recently on a new device and enabled full disk encryption.
When I enter the password, sometimes the system does not recognise it and prompts me to enter it again. When I do that, it gets stuck on the loading screen and never boots. Pressing ESC showed me some error messages about the crypt library.
How can I solve this problem? I am forced to do a force restart at least once a day because of that. The keyboard layout is shown to be de So I don't think it is related to a layout mismatch.
Is it possble to make the login UI visible by default when I click Menu>Lock instead of having to shake my mouse?....For now When I click lock, I only see the background till I shake my mouse
For now I tried editing the UI QML:
/usr/share/plasma/shells/org.kde.plasma.desktop/contents/lockscreen/LockScreenUi.qml
and setting property bool uiVisible: true
Also tried setting the timer OnTriggered to have lockScreenRoot.uiVisible = true instead of false
But all of this ended up in a faulty behaviour where it would work the first time, the other wont and I wont be able to login because of lost focus till I press Esc and try... luckily I restored the file to its original state.
What can I do so the UI of lockscreen shows all time without shaking mouse?
Although Sogou changelog stopped in 2022, I hoped I could still make it work for Ubuntu 26.04 since it worked for Ubuntu 24.04. No luck so far.
fcitx/fcitx5, this seems to be an easy one, following the guide can resolve it.Things I have tried:
The furthest I have been was the input candidate screen flickering a lot.
I know Ubuntu has build-in input methods for many languages, ibus-rime is also an option but, honestly, none of them allows me to type Chinese fast enough - input method application has to bring a good user experience and productivity as it takes all the keyboard inputs -. If it doesn't, it's useless. On Ubuntu, I haven't found my choice; I will need to fall back to Ubuntu 24.04 because of this, sadly.
A friend said he uses the Debian Linux program "Brassero" to turn the DVD into an ISO file (for a 1:1 copy) and then watch it with VLC on my (large screen) computer. My Ubuntu 26.04 won't load Brassero.
I sometimes realise that Ubuntu is adjusting screen brightness slightly when switching between windows and apps. I have disabled Dim Screen option on power settings but it is still doing it. Is there any other setting to disable it? My laptop is a Thinkpad T495.
I use Ubuntu 22.04.5 LTS with Gnome 42.9. I have been using Variety Wallpaper changer for years which I always install from the Ubuntu repository. I have it set to start at startup and my backgrounds to change every 15 mins. It normally works incredibly well but last night, I noticed my wallpaper seemed to have been stuck on a certain image for a while. On further investigation, I found that the app indicator for Variety was missing.
Thinking the app had crashed, I went to re-start it manually from the menus and discovered I couldn't because its icon was not in the Gnome menu. Variety Slideshow's icon is still there and it functions fine. I opened the Ubuntu repository and found that according to the ubuntu package manager, it was still installed on my system. Nonetheless, I uninstalled and re-installed.
Nothing. No change. The icon is missing from the menus even after a system reboot and the program will not run at startup. I checked. The .desktopfile is still there.
I noticed in the forum, someone was having trouble using Variety on my version of ubuntu in dark mode. I use light mode, however.
Any help would be greatly appreciated. :)
My system always restart after I do a poweroff.
I have a Nvidia rtx gpu, msi mag motherboard with the latest bios
I tried with two kernels: 6.12.0-061200, 7.0.0-14, 7.0.0-22
What I tried
Without any warning sign when I last cleanly shut down my laptop running Ubuntu 26.04, it simply won't start again: the screen stays off, all lights are on (power button, ESC key, Shift Lock and Num Lock) and it stays non responsive
Hitting ESC repeatedly does nothing, and I can't boot on a USB stick (Fn+F12 is unresponsive). Other known keys (Fn+F2, Fn+F8) do nothing.
Anything else to try?

GNOME Activities Overview workspace thumbnails begin flickering after several hours of uptime on Ubuntu 26.04 LTS with GNOME Shell 50.1 running on Wayland and Intel Alder Lake-N integrated graphics (i915 driver).
System:
Symptoms:
I’ve tried:
Observations:
Question:
Has anyone seen GNOME Activities Overview workspace thumbnail flickering or corruption on GNOME Shell 50 / Mutter 50 under Wayland, particularly on Intel integrated graphics? Are there known issues, workarounds, or logs that I should investigate further?
Update:
I performed additional testing and found a significant correlation with monitor configuration.
With my original multi-monitor setup (2 ASUS monitors + 1 TCL TV), GNOME Shell produced thousands of repeated errors:
gbm_surface_lock_front_buffer failed Failed to query buffer age, got error 3003
These sessions also exhibited Activities Overview flickering, top-panel flickering, and occasional window-edge artifacts.
I have now tested the system with a single display only (different display: Sony TV over HDMI) and the issue has not reproduced. There is no visible flickering, no rendering corruption, and:
journalctl -b | grep -c "gbm_surface_lock_front_buffer failed" 0
journalctl -b | grep -c "Failed to query buffer age" 0
The issue also reproduced across multiple kernels, including a newer mainline kernel Linux 7.0.12-070012-generic, which makes a pure kernel/i915 explanation seem less likely. Using this mainline kernel the symptoms also started appearing after roughly 10 minutes rather than a few hours.
At this point, the strongest lead appears to be a GNOME Shell/Mutter multi-monitor rendering issue, or an interaction involving multiple outputs.
In Ubuntu versions previous to 26.04 the default mount point for automatically mounted removable media (by GNOME?), like USB drives, external HDDs, SD cards, etc., was something like /media/<username>/<disk_id>/. Now, after upgrade to Ubuntu 26.04, it seems that the location /run/media/<username>/<disk_id>/ is used instead.
The top-level /media/ directory still exists and it is still populated with user directories from past mounts.
Update: There is a short explanation for the "why" this change has happened at the Release Notes for Ubuntu 26.04 and in some answers given below.
My question is: What will happen to the /media/ directory? Is the /media/ directory still created in fresh Ubuntu 26.04 installs? I had upgraded my system to 26.04 from 25.10 and I don't know whether it is still an essential directory or can be safely deleted.
I used to use VNC in x11 but it does not work with Wayland.
How can I connect to my Kubuntu 26.04 (Wayland) computer from another computer in another network so that I can access its GUI, just like in VNC?
Being able to access Wayland with VNC is important because KDE's support for X.Org is going away in 1 year.
RealVNC provides a method to sign in and access your computer from anywhere. But it does not support Wayland. It would be able to use the same feature in Wayland across different networks.
I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.
Is there any way to automate the connection process? AFAIK know Apple's computers have some robust connection procedure with iOS devices.
I want to be able to do this for multiple computers with the same phone.
I installed Wordpress on Ubuntu 20.04 using the following link:
https://ubuntu.com/tutorials/install-and-configure-wordpress#1-overview
Then, I created a website on localhost. Now I need to migrate it to a web hosting to make it live. I did not find the database in var/lib/mysql/my_database_name. Could you tell me where I can find the database of Wordpress? I do not have installed phpmyadmin
As per the title, I get no sound following a fresh install of 22.04. In another partition I have Zorin OS 16 and it works just fine. I followed the instructions in this post HDMI Audio Issue Ubuntu 22.04 but it didn't work. Any help would be much appreciated. Also I am most definitely a noob. I have enough knowledge to move away from Windows & install the os, follow instructions etc. but am at loss when it comes to troubleshooting.
I am using the Wireguard VPN client on Ubuntu 20.04 through the network-manager plug-in. The plug-in reads the configuration file I got from the sys admin, which is below (network-manager also handles the startup and shutdown of the wg client):
[Interface]
PrivateKey = removed
Address = 10.200.85.2/32
MTU = 1412
DNS = 10.200.85.1
[Peer]
PublicKey = removed
Endpoint = removed
AllowedIPs = 0.0.0.0/0
The computers I am trying to reach on the other side of the VPN are in the 10.0.15.xxx range.
This works, except that ALL traffic on my client is routed through the WireGuard VPN. I only want traffic for 10.0.15.xxx routed through the WireGuard VPN.
I have tried changing AllowedIPs to addresses containing various permutations of 10.200.85.x/x and 10.0.15.x/x, It seems that changing AllowedIPs to anything but 0.0.0.0/0 prevents anything from getting routed over the VPN, and "ip route get" shows the route for all addresses going through the primary network connection.
The WireGuard setup in Network Manager also has a "Use this connection only for resources on its network", but checking that with AllowedIps = 0.0.0.0/0 still sends all traffic over the VPN.
I found a post on here Configuring routes so that vpn is only used for local resources showing how to add some routes for a PPP VPN to accomplish what I am trying to do. It basically assigned a route for the desired remote network to the PPP adapter, and then added a route for 0.0.0.0 with a high metric. I added routes as suggested in that article to the Network Manager WireGuard setup, but everything is still routed over the WireGuard VPN. I could see that the routes were added with "route -n", but the high WireGuard metric for 0.0.0.0 didn't encourage traffic to be routed over the primary network connection.
Any suggestions on how to send only traffic for 10.x.x.x over the WireGuard VPN? Probably something simple I am missing. Thanks for any help!
EDIT: Also, it seems odd to me that when the WireGuard VPN is running, there is no route in the route table...

I have old Linux kernel versions that I don't use so I was trying to remove them.

I have an openvpn client and it's configuration is stored in a .ovpn file. All my network traffic is going through the VPN tunnel when I connect to it.
I want to add an exception for some of the IPs to not go through the VPN tunnel. I have tried adding route www.google.com 255.255.255.255 192.168.43.1 at the end of the ovpn file to test it. (192.168.43.1 is router IP address)
But, this is making the configuration file invalid. I am just beginning to learn openvpn and I am confused about where to add this line exactly.
Sometimes, when I log in, a window pops up marked "Web authentication from Google", saying "GNOME Evolution would like to:" followed by a list of things (view and manage mail, view email address etc.
When I enter my login details, the window disappears, then pops up again, and again, and again... Clicking on "Allow" or "Deny" makes no difference, it just keeps coming back. This seems to happen at random occasions on login, and Online Accounts seems to show everything OK.
Why is this happening?
My laptop recognises external display devices if I connect them before booting the system, but many times it doesn't if I connect while the system is running. In this case, rebooting naturally solves the problem.
Is there a way to force Ubuntu to detect external displays? Opening up the display menu and pressing "Detect displays" does nothing.
I know of How to remove an uninstalled package's dependencies? and I tried
apt-get autoremove
but that does not remove dependencies that are recommended/suggested by other packages.
That is, if I install a package X that recommends Y, but I do not install Y, and then I install package Z that depends on Y. and later I do
apt-get remove --auto-remove Z
then Y is not automatically removed even though nothing depends on it. (X "picked up" Y, even though it does not depend on it).
I'm running Ubuntu 12.04 on a Lenovo x61s Thinkpad. As the screen's rather small and I want to do some video editing, I thought I'd plug in a monitor and use that. The monitor is Relisys JM777 (quite old).
When I plug it into my other computer, which is running Windows 7, it immediately mirrors the display; but when plugged into the Lenovo the monitor screen remains blank. The graphics card on the Lenovo is a "VGA compatible controller" according to SysInfo.
Anybody got any suggestions for getting this monitor to work? I'm quite new to Linux.
