Fresh install of F27 and I have a bit of an odd problem kind of in two parts
Installed fine, installed Nvidia stable driver through RPMfusions as usual all ok. On reboot had what seems to be a common problem of really laggy mouse and keyboard input. Searching seems to suggested adding nomodeset to grub solves this. Didn't for me, same problem.
Then by accident I did something odd - after adding nomodeset I was looking at other options, and not meaning to hit CTRL-X to boot without realising I had put a space inbetween q and u of quiet following nomodeset. Anyway, computer booted but grub gave an error saying can't find command q (fair enough!) but it booted with no lag problems and nvidia drivers running fine??? Tried various other things like changing nvidia-drm.modeset=1 to 0, deleting the dot out of it, even randomly pressing enter half way though grub line and it boots as should no problems.
1st problem - What is actually happening in this scenario to stop the lag?
2nd problem - How to make it persistent when I do figure it out?
I tried to edit grub with sudo gedit /etc/default/grub but you now seem to have to use the gedit admin///etc/default/grub instead. Is that correct? I simply added nomodeset here in first instance and then ran sudo grub2-mkconfig to update. This updated it and when I check the file it has saved the change but on bootup grub doesn't seem to read this file? I can hit 'e' to check what its running and its the same default stuff without nomodeset in it?
So - how do I stop the lag without just randomly butchering grub command on each start up and when I do work out what to alter how do I make it persistent across a re-boot?
Standard grub file before any alterations is:
Code:
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
On bootup and 'e' there are other commands listed before this part but not sure how I can show that here?
