From time to time since several months now, I noticed freezes on my TW:
suddenly system went unresponsive and I can't input anything by the
keyboard.

All the apps loaded keep working regularly but I can't input any command
by the keyboard.

Only mouse navigation through the windows is functional.

I red some reports on the Web that this is a common occurrence for Intel
i915 video cards which I'm using here on my Leonovo Z470, then I tried
to modify the file /etc/X11/xorg.conf.d/10-intel.conf by changing former
AccellMethod parameter from *sna* to *uxa*, without any beneficial
effects:

cat /etc/X11/xorg.conf.d/10-intel.conf
Section "Device"
    Identifier "Intel Graphics"
    Driver "intel"
    Option "AccelMethod" "uxa"
    #Option "DRI" "3"
    #Option "TearFree" "true"
EndSection
...
Give it a try to "HUP agetty" to avoid the more drastic system reboot.
For a raw solution you can always add *nomodeset* to kernel to ignore
the Intel driver, but of course it will make you loose the graphical
enhancements.

Nomodeset is for troubleshooting, not actual GUI operation. Nomodeset causes
fallback to the horrible last resort FBDEV or VESA xf86 drivers. Try the
"other"
FOSS driver. If your i915 is not too old or too new, it will automatically be
used simply by removing xf86-video-intel, though I suppose you could make it
explicit in xorg.conf.d/10-generic.conf:

Section "Device"
Identifier "Default"
Driver "modesetting" # (modeset, as shows in Xorg.0.log?)
EndSection

All my openSUSE installations on i915 systems that are new enough (965G maybe,
G31 no, G41 yes) have xf86-video-intel uninstalled.

On host fi965 on 20180704 I have:
# zypper --no-refresh se -s -i input | egrep -v
'debug|devel|srcp|openSUSE-20' |
egrep 'x86|noarch'| sort

i | libinput10 | package | 1.11.1-1.1 | x86_64 | OSS
i | xf86-input-evdev | package | 2.10.6-1.2 | x86_64 | OSS
i | xf86-input-keyboard | package | 1.9.0-1.4 | x86_64 | OSS
i | xf86-input-mouse | package | 1.9.2-2.2 | x86_64 | OSS
i | xinput | package | 1.6.2-1.9 | x86_64 | OSS


Hi and thanks for the hints!

BTW I'm already testing a new *intel.conf* I found on openSUSE Forums
for a similar issue, this is using modesetting:

cat /etc/X11/xorg.conf.d/21-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "modesetting"
Option "AccelMethod" "glamor"
Option "Backlight" "intel_backlight"
EndSection

I will try this setup for some weeks to see if it resolve my freezing
problems.

Cheers,
