I have installed Lubuntu 20.04 dual boot with Win10, i have a issue wich is that when i back from Suspend the system, the screen does not show nothing, only it is black so i must power off/on to can use it again. So i need reinstall Lubuntu 20.04 but without lost soft and configs (example: .sh scripts, startup programs). I was looking for ways to repair this issue but i can not, i tried changing /etc/default/grub, this part: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.dc=1 amdgpu.dpm=1 amdgpu.modeset=1"

if i change this option as default like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash, when i start the system the screen does not show black but does not work well., all pixels only and here is not bars, etc like normal.

I have installed mesa drivers and kvm before, and all was working good until a electric power down during a general update roken my system, so i need to know:

1_For reinstall keeping all soft i need use exactly same instalation medium? i have the dvd lubuntu-20.04.1-desktop-amd64 + a other newer dvd lubuntu-20.04.3-desktop-amd64 2_If i use dual boot, will i see the Reinstall option?

Sorted by: Reset to default
