update broke VGA resolution?

[nittanylion]

I've been using monitor output on my laptop, running it at 1440x900 and the laptop at 1280x800. Every startup, I'd run this command:

xrandr --output VGA --mode 1440x900 --above LVDS

Just updated, restart as request, and now xrandr won't recognize 1440x900. Now:

a@b:~$ xrandr

I am perfectly well aware that I can add new modes in xrandr, or change my setup in xorg.conf. However, before the updates applied in the past 24 hours, everything worked plug-and-play (minus the xrandr command, which I probably could've done in System --> Preferences --> Screen Resolution anyway). I've had horrible nightmares trying to add modelines under Heron, sooo any thoughts on finding out what went wrong?

bumping with new details

Having been relegated to using the xrandr --newmode command every time xserver gets updated, a few new issues have arisen. After I change to a resolution on VGA output, occasionally the VGA output will just die. I can bring up the terminal on the LVDS display and attempt to change the VGA resolution, but no matter the resolution, the VGA monitor shows no input.

Furthermore, since it's detecting my monitor at incorrect resolutions (1360x768? for some unknown reason), I'll add the mode using the proper modeline, and sometimes xrandr will simply ignore the command. No error message, it just will not add the new mode. Sometimes I have to restart the xserver a few times before it xrandr will actually add the new mode.

And for what it's worth, this has always persisted (even before the update that really screwed me over): if I set up an expanded desktop with 2 different resolutions, any attempt to change an individual resolution will crash the xserver entirely.

For all 3 of these details, I have not found any details in various logs that would hint at what's going on. Beyond looking to the logs, I'm at a loss how to troubleshoot this. I'd file a bug report if I had any idea what's causing this behavior.

bumping b/c update did it again

Plus xrandr is giving this error message:
