Screen really weird flickering

Hey, today when i reopened my acer laptop, i saw something really weird. The screen freaks out in somekind of flickering when i move the mouse!! I did a full update earlier and i didnt notice anything strange. I left for a couple of hours shutting down the computer and when i came back this started. I dont have any idea what to do. I post an image to see yourselves too...Plz help!!

Re: Screen really weird flickering

I don't see anything wrong on that screenshot, maybe you would have to record a movie.

Have you tried rebooting?
Tell us more about your setup: list the packages that you've updated, tell us what graphics hardware and drivers you're using, is the anything interesting in the logs or systemd's journal etc.

Re: Screen really weird flickering

Sorry for the screenshot i didnt realise that print screen doesnt show the problem. I took a new one with my phone (You can see how the screen totally "splits". (http://i62.tinypic.com/2uzw7l4.jpg)

I also did lsmod too show you full drivers.. I am a bit noob at arch linux, i have it for about three weeks. So you can tell me what do u want for me to search! This is the print from lsmod:

Re: Screen really weird flickering

If the problem does not show up in a screenshot, that would suggest a hardware issue.

Does the problem occur in (a live version of) a different distribution?

Re: Screen really weird flickering

I didn't try a liveboot yet but i will..this will certainly tell if there is a hardware problem. But when i boot the computer everything is ok. If there was a hardware problem i believe it would occur from the start..

Press F12 or whatever your BIOS "select boot device" key is when you're on the BIOS splash screen and select the USB device - removable device it might be called.

Yeah the normal way is like that..the problem is that in the grub menu only arch linux exists

Re: Screen really weird flickering

Why would the GRUB menu have an entry for your live Ubuntu USB stick?

You need to select it from your firmware (BIOS) options.
