I’m trying to install Qubes on a Lenovo ThinkPad L14 Gen 3 with AMD Ryzen 7 Pro.
Secure boot is off. BIOS version is 4.24.
Qubes 4.2 and 4.1 installers would not boot: When I selected boot from USB, I would get a black screen for a moment, then it would return to the boot menu. I tried installing Qubes 4.0 and it worked, although Qubes was very slow and WiFi did not work.
Next, I tried to update in place using
qubes-dist-upgrade. It seemed to work, but now booting is extremely slow (over 10 minutes). It waits a long time trying to start some VMs. Then, after logging in, the trackpad stops working. I end up looking at the desktop background and nothing else. Eventually that disappears and I am left with a black screen with a small, gray square in the top left, maybe 3x3 pixels.
After rebooting a few times and getting the same issue each time, I got this:
[ 24.811061] watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [mapper/0:0]
The password screen did show up eventually after that, but now I’m running extended hardware diagnostics just in case.
Any ideas what is making this laptop incredibly slow? And any ideas on what is causing the black screen after login?
