Description
since my update from hrev53658 to 53714 my display is distored i have the follwing controller device Display controller (VGA compatible controller, VGA controller) [3|0|0]
vendor 8086: Intel Corporation device 0046: Core Processor Integrated Graphics Controller
My Resolution ist 1366 x 768.
The display is kind of scaled (wrong aspect Ratio?) in the x - Axis ... this way that i cant acces the Deskbar anymore..
changing the resolution to 1024 x 768 kind of helped to display the Deskbar, but the aspectratio is still messed up...
Everything worked find before my update

Since hrev53717 on switch from 1024 x 768 (was my default now) to 1366 x 768. it was still scaled wrong (deskbar out of screen) on swith to a different workspace the screen turned black on switch to a nother workspace it showed crazy colored lines... and then it crashed (kerneldebuggerland... sady i didnt took a photo)

This is not KDL but an app_server crash. You can type "save-report" from there to save a debug report.

The part with the screen turning black:
intel_set_display_mode(14947x24936)
I fear this is something to be fixed in app_server side, if it gives us a mode like this, what should we do?

for your changes ... it rendered the system complete unusable.. :-D only flickering colored line (i can add a picture and syslog later since i have some trouble accesing them :))

If you like i can try to write diffrent values to registers (guided over irc) ... in the kdl... if this helps you... (i dont have any knowledge there yet... but if it helps i can learn ;-))

Yes, the problem is it takes hours of checking and writing values in the registers even if I'm doing it directly sitting in front of the computer. I don't think doing it over IRC is reasonably practical :(
We should meet at some coding sprint or other event where I can borrow your computer and then I may be able to find the problem.
I will see if I can reproduce it here one one of my old laptops or borrow ones from other people around...

Ok, so today I noticed that I can reproduce the issue on my machine. So I will be able to investigate this. It is a newer generation but there is exactly the same problem.
The flickering colored lines are actually "better". What happened before is we were setting a broken video mode on the secondary display, but the LVDS panel was showing the primary one so this was not visible. Now, we set a broken mode on the primary display, and we can see what we are doing.
I will continue investigating this and fix the modesetting. I hope it will also help with other problems.
