Low resolution on my computer/tv screen?

How to fix low screen resolution in Ubuntu Linux? None of the documented fixes are working for me.?

• I have an ImageQuest (Hyundai) Q770 monitor and it only gets either 800 x 600 or 640 x 480 resolution. I've read the thoroughly documented threads on this issue, but no fixes have worked for me. I've followed: https://wiki.ubuntu.com/FixVideoResolutionHowto and http://ubuntuforums.org/showthread.php?t=507777 and numerous others with no success. I've also went to usr/share/applications and found Screen and Graphics, but it could not find my exact monitor type. It does have ImageQuest Q910, but after just trying to select that model just to see if it's equally compatible with mine, it didn't work. The model number isn't under Hyundai, which is in Screen and Graphic's list of monitor's too. Ubuntu went into low graphics mode when I selected the Q910 monitor. I also tried editing the xorg.conf file as such: Section "InputDevice" Identifier "Generic Keyboard" Driver "kbd" Option "XkbRules" "xorg" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" EndSection Section "Device" Identifier "Configured Video Device" Option "UseFBDev" "true" EndSection Section "Monitor" Identifier "Generic Monitor" HorizSync 30-70 VertRefresh 50-150 SubSection "Display" Depth 24 Modes "1024x768" "800x600" "640x480" EndSubSection EndSection Section "Screen" Identifier "Default Screen" Monitor "Generic Monitor" Device "Configured Video Device" EndSection Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" EndSection Any ideas?

• Answer:

  Hi, What video card are you using? You may need to switch over to the restricted drivers on an NVIDIA card (unsure about ATI). You can get the drivers through the Synaptic Manager under NVIDIA-GLX or from the terminal. sudo apt-get install nvidia-glx sudo apt-get install nvidia-settings
