Ubuntu Feisty » increase screen resolution & blue screen error
So i just remember something very important, when playing around with your screen resolution on your Linux box please know what you are doing. Anyhow this is how i managed to resolve two of my problems on Ubuntu Feisty Fawn.
Problems:
1. How do i increase my screen resolution?
ANS: Well there are a number of variables to consider, but i have an Nvidia graphics card so that is the basis. At the time i could only get only get “800 x 400″ at a refresh rate of 60Hz, and this just wasn’t cutting it.
2. I messed with the graphics or default keyboard settings on my Ubuntu box and now there is an error and i am getting a blue screen!!!!?!?
ANS: Do not panic. The screen reads something like “gdm is not properly you need to reconfigure blah blah blah…” This means you fiddled with something relating to the xorg.conf file.
Solution:
NB: know your monitor and its limits! Do not blow it trying to be fancy.
First if your just trying to increase your screen resolution - open up your terminal and and type in
$ sudo dpkg-reconfigure xserver-xorg
at which point a blue screen appears.
If you are trying to get back to the GUI from the blue boot screen - select no when it asks you to troubleshoot or whatever and login to your computer using the terminal. Once there type in
$ sudo dpkg-reconfigure xserver-xorg
at which point a blue screen appears.
Secondly accept all the defaults by hitting enter or tab to get the default selection, and continue till you get to a screen like this
“Many monitors (including LCD’s) and video cards support a communication
protocol that allows the monitor’s technical characteristics to be
communicated back to the computer.”
and select yes to the Attempt monitor auto detection?
Continuing till you get the screen where you select your resolution. BE cautious! and select ok.
Carry on until you get the final screen and select the No option to overwrite the file and you should be done.
Restart the X with the ctrl+alt+backspace and it should reboot with your settings.
