My resolution is stuck at 1024x768. I've read through whatever is available here, ubuntuforums, and the ubuntu wiki. But I can't seem to fix the issue.

I've reinstalled Ubuntu, keeping only my home, var, and opt folders (mounted on other partitions).

I've tried to create a new user (so home folder is different), but still the problem continues. During the reinstallation, the resolution was at the correct value, so I know its not an issue with my monitor. There is no xorg.conf anywhere, and I'm pretty sure its not an X issue, as I tried booting into safe mode once, and it switched halfway through the boot to the lower resolution.

The plymouth boot screen is also the text one.

I thought that since the problem persisted after a reinstall, it should be somewhere due to my home folder, and read that the culprit might be a monitors.xml file, probably inside ~/.gnome2/, but there was no such file.

Right now, my monitor only supports 1024x768, shows the monitor as unknown in Displays, and defaults to Ubuntu-2d.

I'm using Dell Inspiron 1545 (Intel GM45, not ATI/nVidia). I've been through my history, and the only related thing I could find was installing xmonad, and uninstalling it later. Also it refuses to identify an external monitor once I connect it.

Here is my Xorg.0.log file. The output of sudo lshw -C display is as follows :
