Right. Since nothing else works, try a Virtual setting. Forget where it's done(in with the video card stuff I think), but the syntax is

Virtual xdim ydim
e.g. Virtual 1600 900

Then you can really mess things up :-)).

man xorg.conf says Virtual goes in the display subsection of Screen:
Code:
Section "Screen"
        Identifier "Screen1"
        Device    "Card0"
        Monitor    "Monitor1"
        SubSection "Display"
                Viewport  0 0
                Virtual 1600 900
                Depth    24
                Modes "1600x900"
        EndSubSection
EndSection
Yet it still didn't change anything. The file is supposed to be named "video.conf" and placed in the "/etc/X11/xorg.conf.d/" directory, right? Want to make sure I didn't miss something obvious and I'm at fault.

Hmmm.

Presuming you boot to X (runlevel 4 or 5 usually) try going to runlevel 3 (init 3 as root might do it).Then run

startx > x.err 2>&1
See why it's kicking the modes out and notice warnings and errors. It's chucking out your chosen configuration and it's nice sometimes and tells you why.

Well I ran init 3 and startx, but realized I didn't have the external monitor plugged in at the time, so I plugged it in and restarted, but now I can't log in to my system. With the monitor plugged in it says something about being "unable to write bytes: broken pipe", and without it just unmounts everything. Either way it takes me right back to the login screen. Sorry I can't provide more detail on the messages, they flash for about half a second before taking me back to the login page. I already used my liveUSB to remove the video.conf file in case that was messing it up, but apparently something else is. All I recall doing last time I was logged in was reading this thread, installing updates, and then trying the init 3 thing, so I'm assuming it's the latter that's causing problems. Netbook is unusable until I get this fixed since I'm not dual-booting.

Unless things have changed, Ubuntu's default runlevel 3 is the same graphical mode as runlevel 5 (unlike Fedora and many other distros, in which runlevel 3 is text mode).

ohnolawl 05-18-2012 08:58 PM
Yeah when I ran startx after doing init 3 it said that x was already running, but after restarting now I can't log in so I'm unsure on how to progress. I can still log in as a guest or through tty though if that helps.

Ended up just re-installing, think I'm going to call it quits on trying to get this to work, it's not absolutely necessary by any stretch of the word, and re-downloading all the packages I want after wiping is time consuming. I appreciate the help anyway though, learned a few things at least.

Sorry, my bad. You need a text mode for that, to run startx. If I were reinstalling, I'd reinstall something else. Hope you're sorted.
