I have searched online for a solution, I’ve asked around. Nothing. I don’t know what to do here.
I have qubes 4.1 installed on my desktop, had it installed maybe three months. Had qubes on it for at least two years. About maybe 2 weeks ago, I set up a USB qube. Everything was working great. But a couple of days ago, when I tried to boot qubes, during the boot my keyboard and mouse lights would turn off followed by the display completely losing all input 30 seconds later. Then I just had to turn it off with the power button. So I tried instead to boot a different kernel and it worked! I thought it was fixed. Then the next day, NONE of the kernels will boot and they are all displaying this behavior. I don’t know what to do. I have tried text mode, it often happens around the time a bunch of the VMs are autostarting and it sometimes says a bunch of stuff about “USB disconnect” really fast and then goes black. I tried disabling autostart of the VMs to see if that would help, from the grub commandline, and it just started them anyways. (Edit at the bottom, I figured that out and got it to boot after turning that off. but why?)
I am at a loss for what to do. I was in the midst of doing important things on my computer, so this is really upsetting and slowing me down. It’s very important that I get this fixed ASAP as I do not have time to troubleshoot or mount the disk to a live usb and go through the files to try to find what i was looking for etc. I need this fixed yesterday. Would booting a Qubes installer USB do anything to help? Please someone provide some insight, I NEED my computer to work. This is extremely stressful for me. I do not have the time. Thank you!
Edit: I got it the default kernel to work after some fiddling with the grub commandline and turning off qubes autostart. But the question here is why cant I have autostart on? I dont want to have to start every VM when I start the computer. But more importantly, why are my usb devices still working when the usb qube isnt started up? it makes no sense that vms autostarting would make it so my display goes off? Maybe it booting this time is a fluke. Im going to make a backup right now
Edit 2: Just discovered that starting sys-usb is the culprit. But why would it make my ps2 keyboard and my display both turn off? That makes no sense! Can someone help? I checked the devices tab under the sys-usb qube and it APPEARS that only two USB controllers are set up for it and nothing else so not sure why it’d effect my display and ps2 keyboards? I turned off automatic start for sys-usb for now.
