My laptop screen is completely black and I need help to investigate the issue.
Yesterday I was programming as every other day, suddenly some horizontal black stripes appeared on my laptop. I found it annoying and tried to fix it by messing with the "screen settings" configuration on Garuda. I deactivated the main monitor and activated it again. I did the same for the external monitor. Didn't work.
I rebooted the computer.
Now both monitors are black. I can't do anything.
The company that manufactured my notebook claimed that Garuda Linux may have downloaded and installed an Intel or Nvidia driver that is incompatible with my video card, which is why my notebook screen is black.
I have two SSDs, one with Garuda Linux, the other has Windows.
When I turn my computer on, normally the
grub would appear. But now, even the grub does not appear, the screen is black.
But I know that the first grub option is Garuda, and the third grub option is Windows. After I turned the computer on, I pressed down arrow twice and pressed enter, and the computer booted on Windows.
The laptop is still black, but the external monitor is working on Windows. I asked help on
Telegram to recover my linux files, a friendly Garuda member sent me a
brtfs driver, I downloaded it on Windows and I recovered my Garuda Linux files and made a full backup.
Now I need help on how to proceed. I am not sure what is the cause of the problem. Today, I rebooted the computer 100 times, and one of them Garuda Linux worked and both monitors were working! Woohoo, I went to eat something, after 10 minutes, the idle screen was activated by Garuda, and the black screen never disappeared anymore from both monitors.
I still can boot on Windows and use the external monitor.
My question is: is this a physical problem of the laptop screen? Is this a driver incompatibility issue (as the manufacturer claims)? What should I test, what should I investigate?
I would appreciate any input on this. Thanks.
