SLES12 SP3 icewm changing resolution

Unable to permanently change resolution of SP3 using icewm. Previous forum post in 2013 (now closed) had solution that worked on sp2 but not on sp3. This post suggested adding Screen section to /etc/X11/50-screen.conf with the desired resolution specified (1280x1024 in my case).

xrandr --output VGA-1 --mode 1280x1024
will change resolution to 1280x1024 for one session only.

gnome-control-center → Display finds no displays.

yast2 → Bootloader → kernel parameters → resolution setting has no affect on booted sessions

Any ideas how to permanently set the Display Resolution to 1280x1024 with icewm?

I’m guessing you are aware that SLE 12 SP3 is still in beta and is not officially released yet?

That being said, creating a suitable screen section with the Default Screen identifier and Modes “…x…” in 50-screen.conf should still work. Perhaps you could take a peek at /var/log/Xorg.0.log and post it to a pastebin to see why it’s refusing to use your screen configuration.

Got it to work by changing the following in the screen section:

Identifier “Default Screen”
Identifier “VGA-1”

And these are NOT the SLES/SLED forums. These are the openSUSE forums.

So next time better go there and not depend on the few SLES users that visit here.
