I am trying to set this up, and it is not always
clear, what to do/ what is going on.
Currently, X.org log says:
(WW) Warning, couldn’t open module intel
(EE) Failed to load module “intel” (module does not exist, 0)
/usr/lib64/xorg/modules/drivers/intel_drv.so is not present,
swupd repair does nothing helpful;
And the whole interface works with a little delay (compared to any other system), as if acceleration was turned off.
Where to look?
Even after switching to Nvidia GPU, lag is present. No matter what key you press, there is 250~ ms delay. I really need some help here. Just mere reinstall is a shame.
(EE) Failed to load module "nv" (module does not exist, 0) added to X.org log
Cruel-pit (for this particular case) was:
Experimenting with Cuda and Nvidia drivers quickly clogged free space without me noticing it.
Getting free space to 10 % of drive capacity lowered delay significantly.
Meantime I accidentally found out that while Firefox behaves badly, simultaneously launching Slimjet on contrast showed virtually no delay or close-to-no. The same bad behaviour was displayed by Gnome terminal. (So is a software issue. Not drivers or anything.)
Afterwards I have found that fixing very-very-very odd delay of keyboard input (omnibox, inputs, forms) requires:
firefox.conf(you can find examples on the forum/ in mentioned repos)
ffmpegwith hardware acceleration flags.
(Previously it was not able to playback HLS, H264, some audio.)
(Not sure about why Terminal showed same behaviour, but that is for the later to discover Also I totally forgot to mention that after booting into installation media – delay persisted. Once again: software issue.
One more thing: on the same hardware, under different OS Firefox showed the same behaviour, while native browser was smooth as butter.)
