[Bug 1772296] Re: Alt Gr (right alt) key not working after login in 18.04
Alt Gr doesn't work in the login screen for me either. So I have to switch to English layout to be able to login. I'm on a Dell Latitude E7470 Swedish keyboard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772296 Title: Alt Gr (right alt) key not working after login in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1772296/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1939347] Re: Ubuntu 20.04 freeze since kernel 5.11
With my Dell Latitude 7490 running kernel 5.13.0-22 on Ubuntu 21.10, it freezes around the login screen. However, if I boot with my dock (Dell WD15) connected, it seems to work fine. Until I disconnect the dock... then it freezes a few seconds after. I tried both of these mainline versions: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14.21/amd64/ https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.6/amd64/ I get the same behavior.. only works with dock connected. I attached the output of "journalctl -k -b -1" for the 5.15.6 boot without dock. ** Attachment added: "journalctl -k -b -1 for mainline kernel 5.15.6 without dock connected" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939347/+attachment/5544902/+files/journal-5.15.6.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939347 Title: Ubuntu 20.04 freeze since kernel 5.11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1939347] Re: Ubuntu 20.04 freeze since kernel 5.11
In /etc/default/grub, I added the following kernel parameter: GRUB_CMDLINE_LINUX_DEFAULT="i915.enable_dc=0" Then run sudo update-grub and restart your computer. This disables GPU power management. It still freezes for a while, but then it is released and it seems to work. CPU usage seems to be at 100% when it does let go. I can now at least use my laptop without the dock or using the kernel recovery mode trick. You can also try limiting the CPU sleep states by adding: intel_idle.max_cstate=1 Try and see if one or both of those fixes it for you. I haven't had my laptop running for longer periods yet, so I don't know if this just delays the freezes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939347 Title: Ubuntu 20.04 freeze since kernel 5.11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
