I've been running Ubuntu on my machine for quite some time, with a cheap-ass graphics card. A few days ago I went out and bought ASUS GeForce GTX 750, and I dual-booted my system.
Windows works fine, but now Ubuntu acts up. I fresh-installed suspecting that maybe the old drivers and the new drivers were conflicting, but that does not solve the problem. What happens is:
- If I try to boot Ubuntu normally, it displays the Ubuntu logo and the loading dots (in a weirdly low resolution). After playing the login "drum" sound, the screen freezes and nothing helps but hard reboot
- If I try to boot through safe mode, then leave safe mode and go to normal, Ubuntu boots fine
- If I edit the boot order from grub (via e) to remove quiet splash, i get an infinite amount of this error message:
This gets displayed a lot, then freezes and the computer keeps running.Code:[ 31.52...] nouveau E[(blank space here) PMC][0000:04:00.0] unknown intr 0x44000000
What I've tried:
- Installing restricted drivers from the software list. Ubuntu said it can't find any
- Both suggestions on this thread: http://ubuntuforums.org/showthread.php?t=2081649
- Installing manually this driver: http://www.nvidia.com/download/drive...px/73666/en-us
Surprisingly, the last step worked the second time (though not the first). Right now, the status is that I can boot into Ubuntu through safe mode, abort safe mode and it works fine, I think even with the proper drivers, because the resolution is fine and it handles transparency and fade effects well.
So how do I make it boot normally from Grub without all this back-channeling?? I feel like I should simply purge nouveau (that's what's been causing the error messages in the splash I think) but I really don't want to risk it since I've spent all night trying to get to where I am...
I've logged my lshw and dmesg outputs for your pleasure (too big for forum attachments)
