although sougou changelog stopped on 2022(https://pinyin.sogou.com/linux/changelog.php), i still hoped I could make it work for ubuntu 26 since it worked for ubuntu 24. No luck so far.

1. fcitx/fcitx5, this seems to be an easy one, follow the guide(https://shurufa.sogou.com/linux/guide) can resolve it.
2. wayland/X11, that is painful. ubuntu 26.04 uses GNOME Wayland by default. Sogou Linux input method is built for the older X11 stack. it crashes many times. thinks i have tried:
1. GNOME extension: https://extensions.gnome.org/extension/261/kimpanel/
2. switch to X11 - i cannot even log in

furthest i have been was the input candidate screen flacking a lot.

i know ubuntu has build-in input methods for many languages, ibus-rime is also an option, but honestly, none of them can allow me to type Chinese fast enough - input method application has to bring a good user exprience and productivity as it takes all the keyboard inputs. if it does not, it is useless. On Ubuntu, I haven't found my choice; I will need to fall back to Ubuntu 24 bc 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 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

• BIOS set to "Power Off" on AC loss
• ErP Ready enabled
• Wake-on-LAN disabled
• nvidia-powerd disabled
• GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force reboot=acpi apm=power_off nomodeset"

I see this question asked various ways, but I'm asking it anyway.

I'll close the lid on my laptop and it goes into suspend. Then it will wake up at different times. I have looked at power management. Google just tells me how to prevent suspending at all.

Please tell me how I can diagnose and eliminate this quirk. I am running the latest version of Ubuntu with KDE Plasma.

When trying to upgrade from 25.10 to 26.04 LTS I get a message cannot calculate the upgrade. I am told to look in: /var/log/dist-upgrade but /log/dist-upgrade seems not to exist.

Where do I look?

I installed Ubuntu 26.04 on VirtualBox (on Windows 11 25H2 (build 26200.8655)) and started to download files. It runs for a while at maximum speed, then at a certain point it immediately drops to zero. After pausing and resuming the download, the speed returns to maximum, but it drops again soon.

Network adapter configurations are network bridge and Intel PRO/1000 MT Desktop. I tried virt-io as well, but it showed the same issues.

I am facing the same problem, whereas i don't use an external tablet, I have a touchscreen display, the tiling is a problem where when i shrink back the windows it automatically snaps it to the top left corner, this voids me of the ability to move the windows to my desired location. Also the extra cursor in the top left constantly bugs me. I reinstalled ubuntu from scratch and it still is right there. I use a lenovo yoga 7 with amd ryzen 7 and in built amd graphics

We are encountering an issue where a server becomes completely unresponsive, with no clear indication of what caused the hang. example:

As shown above, there are no log entries between 15:45:02 and the subsequent boot at 20:38:14. During this period, the node was completely unresponsive and we were unable to SSH into the server, and there was no useful information visible on the console.

After the reboot, we were also unable to find any relevant messages in the system logs that would help identify the cause of the hang.

we do have following setting:

root@k-w16:~# cat /proc/sys/kernel/hung_task_panic
1
root@k-w16:~# cat /proc/sys/kernel/sysrq
0

kernel.hung_task_timeout_secs = 120

Given that kernel.hung_task_panic=1, we expected to see a hung-task stack trace or kernel panic information if tasks were blocked for longer than the configured timeout. However, no such information was captured in the logs.

i am primarily looking to understand if there additional boot/kernel settings ( sysctl) or debugging mechanisms (SysRq, NMI watchdog etc) that should be enabled to capture diagnostic information during such hangs? - just like exception handler printing stack trace before crashing out.

also, under what circumstances a system can become completely unresponsive without generating hung-task traces or panic logs?

this issue occured with 3 out of 8 servers today within a span of 1 hour.

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?

Lenovo IdeaPad Slim 3 15ABR8

When I restart my laptop if I leave the dock plugged in, then the external monitors aren’t recognized. I can unplug and replug in the dock to the laptop, and I can lock/logout then re-login, but nothing fixes the problem.

When I restart, but unplug the dock so that Ubuntu starts without the dock plugged in, I can plug in the dock at the login screen or after I'm logged in and my external monitors are recognized and work just fine.

I'm using Ubuntu 24.04.4 LTS. The laptop is a Dell pro 16 PC16250 (though this happened with my last Dell laptop also, when I was using the same Ubuntu version). The dock is a Dell Pro thunderbolt 4 SD25TB4. I'm using the display port connections from dock to monitors.

It's a minor annoyance. Is there a configuration file that I need to change, or is there a library that I need to update?

I do not want to install a complete mail stack on my server as we have a mailserver in our network that can deliver emails already. I have a very simple and functioning msmtp setup but it seems that unattended upgrades wants specific packages that procure a program called mailx, mail and sendmail.

I have already tried to just symlink sendmail and mail to msmtp as I remember these programs to have the same command line arguments but running a dry-run with the reporting set to "always" doesn't deliver any mail.

Is there some simple way to set something up that doesn't require me to install the entire emailing stack that comes with bsd-mailx (which includes postfix) and similar packages?

I can't install wine. I put in sudo dpkg --add-architecture i386 and it says error: unknown command: sudo. How do I fix this? I have checked the spelling and even tried using l386 instead as another post suggested, but nothing worked.

I would like to disable mail globally for all cron-jobs in /etc/cron.d/*

I tried the following different approaches without success:

1. /etc/environment: Added MAILTO=""

2. /etc/crontab: Added MAILTO=""

3. /etc/systemd/system/crond.service.d/override.conf:

   [Service]
   Environment="MAILTO="
   

sudo systemctl daemon-reload
sudo systemctl restart cron

I would like to avoid setting MAILTO in every cron-file in /etc/cron.d/ ...

I hope you have some good ideas.

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:

• Ubuntu 26.04 (upgraded from 24.04)
• GNOME Shell 50.1 / Mutter 50.1
• Wayland session (no Xorg session available)
• Intel Alder Lake-N UHD Graphics (i915 driver)
• Three displays (all 1920×1080 @ 60Hz)

Symptoms:

• After several hours of uptime, GNOME Activities Overview becomes visually corrupted.
• Specifically, workspace thumbnails flicker immediately upon entering Overview (Super key or hot corner).
• The flickering is limited to Overview workspace thumbnails and GNOME top bar. Normal desktop, application windows remain stable and unaffected.
• Exiting Overview immediately returns the desktop to normal. Logging out and back in resolves the issue temporarily, but it returns in minutes, rebooting it returns after several hours. No GPU resets, hangs, or DRM errors appear in journalctl.

I’ve tried:

• Kernel parameter: intel_idle.max_cstate=1 Appears to delay or partially change the symptoms, but the issue still occurs.
• Kernel parameter: i915.enable_dc=0 Initially seemed to reduce symptoms, but the issue still returned.
• Tested different kernels (including older kernel) No change in long-term behavior.
• Disabled a couple of third-party GNOME extensions (still using default Ubuntu extensions).

Observations:

• The issue does not affect application rendering or the desktop outside of Activities Overview.
• It appears only after extended uptime (hours), not immediately after login.
• The issue is reproducible across reboots and kernel versions.
• No relevant errors in journalctl related to i915, DRM, or GPU resets.

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?

I have Preserve Battery Health option enabled on Ubuntu 25.10. It is limiting the battery charging capacity at around 80% level but even after shutting down the laptop and turning it on next morning, I see the battery level at 80%.

Doesn't it suppose to start at 100% and go down to %80 and stay there? Since OS have no control on the battery after shut down, it should be charged to the maximum level.

What am I missing?

I just installed Ubuntu 26.04. I am new to all this. I have tried two different tablets, and both had the same issue. When I tried it shows the pointer moving, but I can't click on icons or draw. This is for both Krita and Open Toonz. I hadedownloaded the driver for my Huion Kamvas pro 16. (I also tried my Wacom Intuos pro too). I searched and people blamed a new xwayland update, a few people said it broke it, they rolled back the update. I only have the newest edition. Is there something I can do? Or just wait until they do a new update to resolve the issue?

When I test the tablet and pen in the test area on Ubuntu desktop tablet area properties, it works, the pressure sensitive also works.

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.

I have Ubuntu Server 24.04 LTS installed. I have a Windows 11 Pro virtual machine built and controlled using libvirt/virsh. I setup a network bridge with Netplan.

Ubuntu is using its regular static IP (10.0.0.2), but Ubuntu is also now using the bridge (10.0.0.3), and the Windows VM is NOT using the static IP from the bridge (which was my intent). The Windows VM does get a lease from the DHCP, but it’s not 10.0.0.3. Ubuntu is also sending some of its own traffic through 10.0.0.3.

In my DHCP server it shows three devices (when the Windows VM is on): Screenshot of DHCP server

Netplan has a bridge (br0) configured: Screenshot of Netplan config

The XML config for the Windows VM is “using” br0 and breaks without it. Windows can get onto the internet and I can RDP to it from another device on the network. But only using the other IP address from DHCP (10.0.0.4): Screenshot of interface in QEMU XML config

How do I get Windows to use the 10.0.0.3 bridge exclusively and keep Ubuntu on 10.0.0.2?

Thanks for your help!

I am working inside an Ubuntu 24.04.2 LTS VM having two physical NICs, enp1s0 and enp6s0. I want to create a bridge with netplan that includes only one of these interfaces. I am using this netplan:

DEV2=enp6s0
cat <<EOF | sudo tee /etc/netplan/bridge.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    ${DEV2}:
      dhcp4: false
  bridges:
    br0:
      dhcp4: true
      interfaces:
        - ${DEV2}
EOF
sudo chmod og-r /etc/netplan/bridge.yaml
sudo netplan apply

However, the bridge never receives an IPv4 address from the DHCP server, as shown with ip a:

2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

If I try to get the IP address manually with dhcpcd --debug br0, but I only get a link-local address (169.254.107.157/16):

Using Openvswitch, by specifying openvswitch: {} option in the netplan, makes no difference. Why does not br0 get an IPv4 address? I explored different paths, like setting the same MAC address for both the bridge and the interface, but with no success (EDIT: turned out I may have misconfigured the netplan, see my answer). I have also enabled IP forwarding and ARP proxying, but they have not changed the situation:

sudo sysctl -w net.ipv4.ip_forward=1
sudo sysctl -w net.ipv4.conf.${DEV2}.proxy_arp=1
sudo sysctl -w net.ipv4.conf.${BRIDGE}.proxy_arp=1

Does the VM need additional configurations?

I have dual-booted Ubuntu 22.04 from Windows. My headphones worked as normal on windows, but when I plug them in whilst using Linux, the sound still comes from the speakers.

I believe the headphones are indeed still being detected but the audio itself still comes from the speakers rather than through the headphones.

I have also tried using pavucontrol, but to no luck so far.

Any help would be much appreciated

I have two MPV media players installed of different versions. One is via apt and another via flatpak. I need them both for different purposes. But they have exactly same name and icon. So, whenever I want to play a file by right clicking on it, I can't tell which one is which. Only if there was a way to differentiate then that would be awesome. I'm on Ubuntu 20.04.

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.

List of installed kernels from dpkg --list | grep linux-image

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?

A little discussions alike this what is a fame of Askubuntu hints me to ask for community opinion due to this is a "multipolar" theme and adequate answer written normal English at the normal user guide nonexistent and what is presumably deliberately situate the crowd.

Though obviously the answer resides extant taxon of the well meaning.
What I wait from community it is all about ubuntuuser-idgroup-idgid

Question: What is normal reason for changing user ID?

My system is auto-mounting as read only and I have no idea why.

I have searched all night including: Ubuntu 12.04 SSD root frequent random read only file system

I have no idea why this is going on. I did run fsck at boot and it didn't find errors.

The disk is fine (500GB, user 38GB)

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 have a dual boot PC with Windows 7 and Ubuntu. I upgraded from 12.04 to 12.10 and then to 13.04 and since then I have not been able to boot because the PC goes into grub rescue with the error "File not found".

I have tried the following steps:

set prefix=(hd0,msdos5)/usr/lib/grub/i386-pc
set root=(hd0,msdos5)
insmod linux

I get error:

symbol not found : 'grub_realidt'.

if I do insmod normal, I get error

symbol not found : 'grub_disk_dev_list'

I have two partitions containing linux file system: (hd0,msdos5) and (hd0,msdos6). They were mountpoints for / and /boot respectively.

I have searched for this error, and found some "solved" threads. But all of them are using Live USB to get in grub prompt. I don't have access to one, and was hoping to be able to solve the issue without a flash drive.

Please help... Thanks in advance.
