I have a multiboot setup, however these days I mainly run Linux Mint due to a stupid bluetooth bug between multiboot linux/windows setups (If anyone can help me with this I'll be immensely grateful visit the end of this issue https://discord.com/channels/628978428019736619/1194022783945027725). The issue is, everything was working fine, however out of the blue since the past two days, I have been getting a random frozen screen. It may occur 2 minutes into booting up or not even after 3 hours of using the laptop. No particular button/key press seems to trigger it since my laptop has also frozen immediately after booting while still sitting on the desktop with no apps running. Tired of restarting, I once left it for one hour at the frozen screen only to come back to the same thing. It does not let me go to a tty, the keyboard shortcut for restarting does not work (I have to long-press the power button). The only things I can think of that may have started this may be:
- I copied some user themes/icons folders to the system themes/icons folders so that root windows also stay the same theme.
- I used BleachBit once (without root one) and also without the free disk space option although looking at the mint forums this does not seem to be such a good program for linux as compared to windows.
- I had originally installed the edge ISO and so was on the 6.5 kernel after updates, when these freezes started happening, I thought maybe it due to the kernel (many forum threads stated this) and changed to the 5.15 (latest). The issue was still not resolved
- In my sheer stupidity I did not follow the standard Linux mint 21.2 to 21.3 update procedure thinking that maybe LTS releases (never) get the new update. I know I know don't laugh at me so I followed an online guide to upgrade that basically entailed "sudo apt update && sudo apt upgrade" and then something like "sudo dist-upgrade" then rebooted.
- I use Grub Customizer to rename/delete some entries and set custom themes.
