Public bug reported: I just installed Kubuntu 19.10 on my brand new Dell XPS 15 7590 laptop.
The display freezes quite regularly for a couple of seconds. In that period, the mouse pointer does move, but nothing else happens: I cannot interact, move windows, scroll, type or whatever. Afterwards the system becomes responsive again. In the kernel log I see messages like: [ 2110.867998] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0 [ 2110.869007] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 [ 2120.523573] iwlwifi 0000:3b:00.0: Unhandled alg: 0x71b [ 2146.443128] iwlwifi 0000:3b:00.0: Unhandled alg: 0x71b [ 2173.551329] iwlwifi 0000:3b:00.0: Unhandled alg: 0x71b [ 2204.008717] iwlwifi 0000:3b:00.0: Unhandled alg: 0x71b [ 4404.960469] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 [ 6020.935285] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0 I found that this problem occurs significantly more frequent when I'm using Jetbrains IntelliJ IDE, but I did experience it in several other occassions as well. I found similar reports both in UBuntu as other places that seem to be related: https://bugs.launchpad.net/ubuntu/+source/linux-signed-5.4/+bug/1863087 https://bugs.freedesktop.org/show_bug.cgi?id=111805 https://bugs.archlinux.org/task/64725 https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1862865 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861395 The ones on Launchpad are marked as invalid for Eoan and only apply for Focal. The XPS 7590 has a Intel chip and nvidia chip, I'm experiencing the problem both with and without the nvidia driver loaded. I ran apport when it wasn't loaded to make sure the kernel isn't tainted with it. Based on the feedback I see that this may be fixed in the most recent releases of kernel 5.4 (>= 5.4.0-17) but I don't see a proper way to install this in Eoan.
