Manjaro boot issue [Solved]

I've started using Manjaro; since well today and I have encountered an issue when booting.

I was messing around and pressed ctrl-alt-del, the screen went black (with a blinking underscore in the top right) and I cannot boot into the OS.

Upon rebooting I used ctrl-alt-f1 to see if the OS was giving any errors, all of list said things that started up is 'OK' however at the bottom of the screen it shows the following message:

"[drm:intel_uncore_check_errors [i915]] *error Unclaimed register before interrupt"

Have patience with me as I'm new to this distro and relatively new to linux

Ctrl-alt-f7 freezes the machine

Would be nice to know how, just for future references. Someone may find it useful.

Upon fumbling around with different kernels, I managed to get a GUI up and running. The heart of the problem was a intel_vesa driver which I installed the same day of the problem.

Major derp; however if this happens to anyone else I would recommend login in as root (using the Ctrl-Alt-F2>F6) and then using the sudo mhwd-kernel command to install the latest or the 'most' stable kernel available.

It has taught me to read the Wiki

I was literally writing it up when you posted that :P

Even though I may have cursed quite a bit during the process it is nice finding answers to the problem.

That timing :D

6

I think a good practice (for me anyway) would be if you install a driver, restart the machine. I hadn't!
Then when I randomly pressed Ctrl-Alt-Del the GUI restarted; and because of the wrong driver then crashed my machine.

7

But still, why did you install vesa in the first place?

8

Simply I do not know. Had some screen tearing which I was trying to fix

9

Did you try using 

Option      "TearFree" "true"

Inside your xorg.conf?

10

I'm assuming I make the changes within the '90-mhwd.conf' file which is located within the xorg.config directory?

11

Post the content of that file. Also what is your GPU? Intel right?

12

GNU nano 2.5.0 File: 90-mhwd.conf

Section "Extensions"
Option "Composite" "Enable"
Option "RENDER" "Enable"
Option "TearFree" "true"
EndSection

Section "InputClass"
Identifier "Keyboard Defaults"
MatchIsKeyboard "yes"
Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

That should be it hopefully in a readable format

Yes 4000 series

14

Well it seems that you already have the TearFree option enabled. Are you experiencing any tear?
Or you just added it?

15

Just added it there, still experience minor tear. Would changing to the propriety driver change anything?

16

Do you have xfce as Desktop Enviroment? If yes try On Xfce goto Settings>Window Manager Tweaks>Compositor and check "Synchronize drawing to the vertical blank".

Or you can run compton with the GLX backend:

sudo pacman -S compton
compton -b --backend glx

Log out and log in to see if it works.

Both the previous option and the "Synchronize drawing to the vertical blank" option seem to have fixed this!

Thanks :D
