(EE) intel (0) : Couldnt allocate video memory



This is what it shows , i cant even loggin to my Ubuntu , now using stink Windows , plz help me what to do , facing for the first time this type of strange error

im not saying this is for sure your problem, so dont panic. ok? i seem to remember (when i was in middleschool, i think) we had a similar problem with a power surge and it screwed up our computer. we had to replace it.

anyway, what you might try is to open up your case, assuming you arent on a laptop, or one of those sealed up compaq things, anyway and test your connections with things like video/graphics. it may also be that the surge managed to reset your display driver, this is unlikely but stranger things have happened. there is a reason they tell you not to turn stuff off while saving/updating

i might also be totally wrong. ive never really seen anything like this, beyond the thing i mentioned above, but that was a *huge* thing. i mean it melted the surge protector, and burned the carpet. im not kidding

Try rebooting into Recovery mode, and select xfix, then restart.

I cant go to recovery mode , when i do it it just perform memory test and takes it a long time , nothing more ..
OK seems to get reinstall the whole Ubuntu , thanks for every one who supported me

Try the cable connections.....
 

I had the same thing happen to me so I checked the monitor cable and found it was loose (Do this with ALL power off) after reconnecting the cable all was ok.
