> Unless you are running proprietary drivers, the instructions for doing this are difficult and should not be undertaken unless you are experienced editing your xorg.conf file on ubuntu. ----- = Text is Blurry on my CRT = Go to "Customize Look and Feel", turn off Subpixel Geometry on the Fonts tab. ----- = Can't Change to Screen Resolution I need For My Monitor or Laptop Screen = == Monitor Settings == Does "Monitor Settings" in the Preferences sub-menu not list the resolution you need? Make a note of the video chipset you have, for example "ATI Mobility Radeon™ HD 5430 Graphics" and head to the [[ http://ubuntuforums.org |Ubuntu forum ]] for help. Also mention your version of Lubuntu. Alternatively, you can use the xrandr (in the terminal) directly. More info [[ https://wiki.ubuntu.com/X/Config/Resolution |here. ]] ----- == Screen resolution is wrong, no matter what I do == === Quick fix that often works === Maybe it will help if you edit the file '''/etc/default/grub''', (remove '''#''') {{{ sudo nano /etc/default/grub }}} from {{{ # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console }}} to {{{ # Uncomment to disable graphical terminal (grub-pc only) GRUB_TERMINAL=console }}} and make it active by running {{{ sudo update-grub }}} and reboot the computer. ---- === Sometimes it takes real tweaking to solve the problem === This needs some real tweaking, mostly from console (tty aka teletype). First we need to get to the console and it is done by pressing following keys: {{{ ctrl+alt+f1 }}} Login with your credentials. After login, we need to stop LightDM (or LXDM, GDM, or KDM) with the command {{{ sudo service lightdm stop }}} Now we can access X Window System for making an Xorg configuration file with the command {{{ sudo Xorg -configure }}} Then we have to move the new configuration file to a correct place. {{{ sudo mv xorg.conf.new /etc/X11/xorg.conf }}} After this we need to edit '''xorg.conf''' a little, actually we need to add our desired resolution. We need to find a section "Screen" and make sure you have Modes "Reso x Lution" there like you can see from bottom. {{{ sudo nano /etc/X11/xorg.conf }}} {{{ Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1024x768" EndSubSection }}} Now you have edited xorg.conf, you can save it and then you need to start LightDM with command {{{ sudo service lightdm start }}} And you should have a correct resolution when you press {{{ ctrl+alt+f7 }}} To return back to X Window System. ----- = My machine doesn't remember brightness settings = There is a known issue with 11.10 when it comes to brightness. Your machine doesn't remember your brightness settings and everytime you reboot, it back to the maximum value. There is a simple workaround for this - '''please see [[http://askubuntu.com/questions/3841/desktop-doesnt-remember-brightness-settings-after-a-reboot | the main reference]]'''. From Terminal {{{ gksudo leafpad /etc/rc.local }}} comment out the {{{ exit 0 }}} by adding # in the begining. Then add this line after that: {{{ echo 0 > /sys/class/backlight/acpi_video0/brightness }}} replace '''0''' with the required brightness value ( ranges from 0 to 10 ) The file will look like this: {{{ #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #exit 0 echo 0 > /sys/class/backlight/acpi_video0/brightness }}} Save the file and exit. Reboot your machine to make sure it works.
