Screen Resolution Issues (For a Learner)
I am new to Ubuntu and linux and not very computer savy. However, got a Dell D610 that came loaded with Ubuntu 8.04 and it was working well for a few days. It then suddenly changed screen resolution to 640 X 480 at 60Hz and will not allow me to go any higher. This was not the case when I got the laptop. I am looking for someone patient to walk me through how to change the resolution back to 1000 and higher x something else. Sorry for the vagueness, as I said not very comp savvy and new to Linux and Ubuntu.

I usually resolve this problem by finding the correct monitor parameters manually and putting it into configuration file xorg.conf. So, you have to: 1. find the parameters launch the terminal and use either gtf or (better) cvt utility to get the proper modeline for your monitor. You should get something like this: Code:
jl@nch-002:~$ gtf 1280 1024 60 2. insert the parameters to /etc/X11/xorg.conf (You will need root privileges to edit this file.) Code:
sudo gedit /etc/X11/xorg.conf 3. restart Xserver You may search the LinuxQuestions.org to get more information about your problem, it is quite common. Good luck. |

(you might want to create a backup of the xorg.conf file first, so you would do: Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup Code:
sudo pico /etc/X11/xorg.conf Then, to save the file, hold CTRL+O then to exit the file editor, hold CTRL+X To summarise the above commands a bit for you: sudo = Super User DO, means the following command will be done with Super User privilidges. cp = copy! pico = is a text file editor (one of many) 'nano' is also another option /etc/X11/xorg.conf = simply the path and the filename.

Hey guys, thank you very very much for your help. The Sudo command worked and my computer is back to normal and now working fine.
When I entered: sudo pico /etc/X11/xorg.conf I got a prompt telling me "If you have edited this file but would like to be automatically updated again run the following command: sudo dpkgpreconfigure -phigh xserver-xorg This enabled any upgrades or downloads to recognise that there was an error in settings and restore the correct resolutions. Computer now back to normal resolutions and working fine. However half another question now, if the text is too small and I keep needing to use the ctrl + + and ctrl + - commands to get it to a useable size. Is there any way of setting it to my own personal preference? Again cheers guys. |
When is the text too small? In the web browser? The application menu? In a terminal? On the login screen?
Or is it too small everywhere? |
