Problem with Screen Resolution

[cause4concern]

I'm glad I helped at least a little bit. It seems you may have a bit different problem than me, I was just hoping the same solution would work for you.
I don't know what is the "gamma output" problem about, you have to google that on your own. However I do have one more piece of advice. The "VGA1" parameter of the xrandr command has to be replaced with one that's valid for your computer, for example, in my case it was VGA-0 (with the dash). You can find out what it is, if you install a package named ARANDR and run it from System => Preferences.


good luck

I have ARandR already installed, but where in that software can i know which VGA is with me.

Just finished a similar scenario last night. Attempted to upgrade to 10.10 thru update manager. All went well until reboot, which almost immediately shut down to black screen. Restarted in recovery mode and ended up with the resolution issue you describe. Finally figured out my nvidia driver was gone/not working. Managed to get into system>administration>additional drivers and downloaded/installed nvidia version 173. Problem resolved. But, now, About Ubuntu tells me I'm running Ubuntu 11.04 Natty Narwhal. How can that be?
Good luck,

You can reveal your version of Ubuntu by clicking System => About I'm sorry but everything else at this point goes beyond my Linux knowledge, I wish I could help more. I just started reading the Linux Administration Handbook, which I got for XMAS. Perhaps I can help in a few months

Nope. They don't show, because of the screen resolution issue. Keystrokes Alt+F1 should reveal them, tho.

I don't know about that, but running lsb_release -a in a terminal will tell you what version you really have.

Then, there's this bug report:

Yes, i think you are right. It is a bug.
I thought that you have upgraded to Ubuntu 11.04 Natty Narwhal by typing "update-manager -d" in the Run Application(press Alt+F2) but i think i was wrong.

But when I press Alt+F1 my Applications Menu is opening.
