Corrupted fonts after resume from ram

I've finally found searching across many forums the solution for my i915 graphic card.

My card is: "Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)".

The problem is: After resuming from ram, some letter have a missing orizzontal line, for example I see ¦ instead of |. Another thing is that sometime, after resuming, the cpu goes to 100% of usage with no apparent reason.

The solution is: Create the file /etc/modprobe.d/local.conf (if it doesn't already exist) and add to it the line "options drm_kms_helper poll=N".

I cannot understand this mystery but now I can use "Suspend to ram" as many times as I want. —This unsigned comment is by Livix (talk) 13 August 2013. Please sign your posts with ~~~~!

There is no i915.powersave option

It's probably some mistake. I have an HD Graphics 4000 and I note no "powersave" option in output of modinfo -p i915 and systool -m i915 -av commands. This is the output of both commands: modprobe, systool.

Lack of powersave parameter for i915 confirmed as of today with xf86-video-intel 1:2.99.917+691+ga77397a-1 (on both an Atom Pineview and Core i3 Ivy boxes). Also by dmesg:
[    0.980110] i915: unknown parameter 'powersave' ignored
[    1.069323] [drm] Initialized i915 1.6.0 20160229 for 0000:00:02.0 on minor 0

What is this: and do we need it? Greyltc (talk) 19:53, 7 January 2016 (UTC)

[drm:intel_pipe_update_start [i915]] *ERROR* Potential atomic update failure on pipe A

Maybe the solution to get rid of the above dmesg log spamming could be mentioned? You just add `options i915 enable_psr=0` to the file `/etc/modprobe.d/i915.conf`. Bjourne (talk) 17:04, 19 August 2016 (UTC)

The new intel driver is a little bit faster than modesetting

Modesetting was faster and better then xf86-video-intel, but after 09/04 upgrade, xf86-video-intel is 10%-20% faster. Do you noted the difference?

Nope, unfortunately the driver is still to buggy to see any real progress happening. I am fighting screen stuttering without any success, see Talk:Dell XPS 13 (2016)#Screen stuttering. -- Edh (talk) 08:24, 16 September 2016 (UTC)
