Wrong Kernel Source #581

Closed cement-head closed 2 years ago

cement-head commented 3 years ago

Trying to use on a System76 machine.

Script won't recognise linux-source-5.11; wants to install linux-source & linux-source-5.4

Barabazs commented 3 years ago

Can you post the output of the install please?

cement-head commented 3 years ago

Nope, locks up and crashes. No output generated.

Barabazs commented 3 years ago

I'm not sure if this is related to how displaylink-debian tries to install dependencies. All we do is specify the packages, without any version numbers.

I would appreciate it if anyone can submit install logs or additional details.

ryepup commented 3 years ago

I also have a System76, and working through display link troubles. I'm uninstalling some stuff to get to a "clean" state then will get an install log.

One possible clue; looks like the default linux-source package is 5.4:

Ok, got an log of the install using script. Removing some progress bar noise and script's formatting I've got:

Reboot now? [Y/n]

At this point my X server froze, and I had to use another terminal to reboot.

Right now I'm in a semi-working state where I have multi-monitor support but my computer freezes if I try to:

I tried uninstalling and then changing the script to identify my nvidia card:

 drv=$(lspci -nnk | grep -i vga -A3 | grep 'in use'|cut -d":" -f2|sed 's/ //g')
-drv_nvidia=$(lspci | grep -i '3d controller' | sed 's/^.*: //' | awk '{print $1}')
+drv_nvidia=$(lspci | grep -i 'RTX' | sed 's/^.*: //' | awk '{print $1}')
 cardsub=$(lspci -nnk | grep -i vga -A3|grep Subsystem|cut -d" " -f5)

Install went basically the same as above, but my /etc/X11/xorg.conf.d/20-displaylink.conf now has all the nvidia settings.

I'm still getting freezes when I change monitor settings, going to try uninstalling/reinstalling with linux-source-5.11 instead of 5.4

ryepup commented 3 years ago

I tried using a kernel-specific version of linux-source, no luck:

 else
-       deps=(unzip linux-headers-$(uname -r) dkms lsb-release linux-source x11-xserver-utils wget libdrm-dev libelf-dev git pciutils)
+       deps=(unzip linux-headers-$(uname -r) dkms lsb-release linux-source-$(uname -r | cut -d'-' -f 1) x11-xserver-utils wget libdrm-dev libelf-dev git pciutils)
 fi

The install log was basically the same as above, but installing linux-source-5.11.0 instead.

ryepup commented 3 years ago

made a separate issue for the nvidia detection and put up a PR: #596

I think the root problem here is the upstream linux-source package hasn't been updated right. I'm unclear of the impact; I see no difference in behavior when I use linux-source-5.11.0 instead of linux-source-5.4.0, but I've got other issues conflating the matter.

Best guess is this is an issue for https://packages.ubuntu.com/focal/linux-source, not displaylink-debian
