Dell M3800 with Nvidia Quadro K1100M
Arch 4.7.2 with KDE Plasma Desktop
Scenario 1
Approx a month ago i upgraded from kernel 4.6.3 to 4.7.1 along with other packages.
After upgrade i was able to login to KDE desktop but after some time display suddenly go blank with few diagonal lines.
It happens suddenly with no pattern. Sometimes i happens within 1 or 2 minute, but some times i was able to work up to 10 minutes.
Once display go blank, keyboard also stop working, I tried to switch to different ttys [Ctrl-Alt-Fn sequence] but no luck, the only option is to keep pressing power button to turn it off.
I was thinking there could be some issue with drivers, so i rollback entire upgrade and revert back to 4.6.3 by doing a restore from backup.
Scenario 2
After waiting a long, i see a new update for 4.7.2. So today i did an upgraded to it.
But unfortunately, still getting the same issue.
But this time i do not want to go back to 4.6.3, instead want to fix the issue.
What i already did is, i downgraded mesa and intel packages to the version that i was using with 4.6.3, but it doesn't make any difference.
Here are packages that i have installed now
lib32-mesa-11.2.2-1-x86_64.pkg.tar.xz
lib32-mesa-libgl-11.2.2-1-x86_64.pkg.tar.xz
mesa-11.2.2-1-x86_64.pkg.tar.xz
mesa-libgl-11.2.2-1-x86_64.pkg.tar.xz
xf86-video-intel-1__2.99.917+676+g26f8ab5-1-x86_64.pkg.tar.xz
What else i should do to fix the issue.
Please suggest.

Forget to mention, my laptop has two graphic cards
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
02:00.0 3D controller: NVIDIA Corporation GK107GLM [Quadro K1100M] (rev a1)
I do not know which one is being used.

Immediately after starting KDE session, if i switch to tty2 [Ctrl+Alt+Fn2] then again switch back to tty1 [Ctrl+Alt+Fn1] then problem doesn't happen.
Is there any linux guru who can help to find out root cause of this issue? i can provide required logs etc.
I can live with above trick but it will be good to fix it from the ground, may other users also getting same issue.

I'm getting some of the same error messages (specifically the xf86CloseConsole ones) and X crashing right when I startx with i3 but then working when I try it again. I've also had diagonal lines, etc garbling the screen sometimes. I removed xf86-video-intel and now don't seem to have the issue. I know you tried downgrading, but have you tried completely removing it?

xf86-video-intel is not required for using Xorg. Xorg will fallback to modesetting. See the first note on the wiki page: https://wiki.archlinux.org/index.php/Intel_graphics
