Hello there guys
As documented many times on the internet, some computers may have problems with freezing when using Ubuntu, and even though I've found many different posts about this particular problem, I've not been able to solve it.
My problem is quite simple; sometimes my laptop (Ubuntu 20.04 LTS) freezes with a black screen when it locks the screen. If sound is playing at the time, the computer will play the last about half a second of the sound repeatably. Trying to change TTY with Ctrl+Alt+F# does nothing. Pressing Caps Lock, the light on the keyboard does not turn on.
The freeze might be worse at larger loads, but am not entirely sure about that.
The only solution to the freeze is a hard shutdown by holding the power button.
I'm using a Dell Latitude 7490 laptop, which includes a Intel(R) Core(TM) i7-8650U and Intel UHD Graphics 620. Most of the time I am also using an external monitor for work.
I've tried many possible solutions to no avail. Some of these include:
- Increase Swap size to 8Gb (8 chunks of 1Gb)
- Install another version of Ubuntu (20.10 to 20.04 LTS)
- Disabled secure boot
- Using
in the grub configuration according to https://linuxreviews.org/Intel_graphics because of the Kaby Lake Refresh CPUCode:intel_idle.max_cstate=1 i195.enable_dc=0- (A couple more which I've forgotten )
Settingseems to make the problem go away (not entirely sure) but is not feasible as a long-term solution.Code:nomodeset
I hope anyone have any ideas to a solution
