Test 1
Then errors. |
I installed:
" linux-lowlatency " which installed kernel 5.4
Then I installed
linux-lowlatency-hwe-20.04
linux-lowlatency-hwe-20.04-edge
which installed kernel 5.8
Questions:
1. Is any documentation for what it is "hwe" and "edge" from
"linux-lowlatency-hwe-20.04-edge" ?
2. I use Linux Mint 20.1 and kernel lowlatency sometimes nvidia driver not working. More often does not work.
I've compared Xorg.0.log with Meld and
with low latency is missing line for example:
-------------------------
[ 13.804] (II) xfree86: Adding drm device (/dev/dri/card0)
[ 13.806] (**) OutputClass "nvidia" ModulePath extended to "/usr/lib/x86_64-linux-gnu/nvidia/xorg,/usr/lib/xorg/modules"
-------------------------
Then with lowlatency kernel I have
--------------
[ 13.187] (EE) [drm] Failed to open DRM device for pci:0000:01:00.0: -19
...
[ 13.188] (EE) Screen 0 deleted because of no matching config section.

I installed:
" linux-lowlatency " which installed kernel 5.4
Then I installed
linux-lowlatency-hwe-20.04
linux-lowlatency-hwe-20.04-edge

Questions:
1. Is any documentation for what it is "hwe" and "edge" from
"linux-lowlatency-hwe-20.04-edge" ?
2. I use Linux Mint 20.1 and kernel lowlatency sometimes nvidia driver not working. More often does not work.
I've compared Xorg.0.log with Meld and
with low latency is missing line for example:

I installed:
" linux-lowlatency " which installed kernel 5.4 and I had very low resolution.
Then I installed
linux-lowlatency-hwe-20.04
linux-lowlatency-hwe-20.04-edge
which installed kernel 5.8
Yesterday kernel lowlatency worked, today not working with nvidia.
I tried update system today, but it not helped.
Questions:
1. Is any documentation for what it is "hwe" and "edge" from
"linux-lowlatency-hwe-20.04-edge" ?
2. I use Linux Mint 20.1 and kernel lowlatency and sometimes nvidia driver not working. More often does not work.
========================================================================
I've compared Xorg.0.log with Meld and
with low latency is missing line for example:
