Re: [opensuse-factory] Force disable LVDS Downclock on intel graphics?

2 Aug 2012

      I have updated to 3.5 and still no change.

The problem seems to persist for the first half and hour or so of
usage, then after that i can connect my laptop to an external display
without random switching. It does appear to happen all the time when i
am running of battery only.

The only thing i can do to make the display usable again is by
unplugging display cable and killing X with ctrl-prntscr-k.

This problem occurred frequently before when i had used the
"i915.lvds_downclock=1" option, but disappeared after disabling, so
i'm assuming it is related to this.

Will try forcing lvds_downclock=0 option and then try vanilla kernel.

Cheers,
Trent

Sorry for the delay in responding.
I can't remember exactly what the last kernel was, but i'm guessing it
was 3.4.5.
Have not tried kernel-vanilla-3.4.6, i am running kernel-desktop.
I have noticed that there is a new update to 3.5, so will update to
this and see if that improves anything.

Trent

However since i ran zypper dup last week and updated the kernel to
3.4.6-34, this display instability has returned.
What was the last working kernel? 3.4.5? Does kernel-vanilla-3.4.6 work?
thanks,
