Question Display Settings in Ubuntu - Karmic Koala


Hi Experts,

I have installed Karmic Koala version of Ubuntu. Now, I see that the pixels are set by around 640 by 480 pixels. How can I change it?

Kindly guide me.

Thanks in advance,
Kannan

Note: I have an LG Flatron W2043T Monitor. Should I load any drivers for it? Then, where to find any Linux drivers for it?

Usually Ubuntu will correctly determine your optimum display settings and set the screen resolution accordingly. In your case it looks like this has not happened.

A few things to try:
System > Preferences > Display see if you can set the resolution there.

If it only offers you 640x480, then try this:
Make sure you are connected to the internet, then
System > Administration > Hardware Drivers
Ubuntu will search for available proprietary hardware drivers. If a display driver appears in the list, then you are in luck. Just click to install it.

You should not need a driver for the monitor.
It would be helpful if you could tell us what video card is in your computer. If you have an nvidia or ati card you should go to: System > Administration > Hardware Drivers, and install the proprietary driver as recommended by Mericet. Then reboot the computer.
If you have an intel graphics card, your best bet would be to try using xrandr as discussed here:
https://wiki.ubuntu.com/X/Config/Resolution
Write back if you need more help.

And welcome to the LQ forums! Welcome to the cool side of computing!

Hi,

I have this problem too. How do I find out whether my card is nvidia/ati or intel graphics?

Thanks

Have a look at the xorg log file. While it's tedious reading, somewhere in the file (usually several places) you will find a line that identifies your display driver/chipset. The log file is located in /var/log and is named something like xorg.log or xorg.0.log. A sample line from my log file is:

(--) PCI:*(0@0:2:0) Intel Corporation 82Q35 Express Integrated Graphics Controller rev 2, Mem @ 0xe0380000/524288, 0xd0000000
/268435456, 0xe0200000/1048576, I/O @ 0x00003430/8

Which identifies the graphics controller as one of the Intel integrated graphics chipsets. Looking a bit farther down, I find this:

(II) intel: Driver for Intel Integrated Graphics Chipsets: i810,
i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G,
E7221 (i915), 915GM, 945G, 945GM, 945GME, 965G, G35, 965Q, 946GZ,
965GM, 965GME/GLE, G33, Q35, Q33,
Mobile Intel® GM45 Express Chipset,
Intel Integrated Graphics Device, G45/G43, Q45/Q43, G41

There it is: The intel GM45 Express. (The actual chipset is the 945GME, which belongs to the GM45 class.) You should see similar stuff for your graphics card.

Note that there is also an abundance of information about the monitor that X identifies at startup, what mode is selected and what modes the monitor has reported as supporting - you may need this later on.

Sorry - forgot to say what I did ...

I read https://wiki.ubuntu.com/X/Config/Resolution

got some info from xrandr

and then created my home .xprofile thus:

xrandr --newmode "1024x768" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
xrandr --addmode VGA1 1024x768
xrandr --output VGA1 --mode 1024x768

I guess it would be better to change xorg.conf ? (where is this - it's not in /usr/X11?), but I'm the only user on the pc so for now .xprofile is ok ...

Newer versions of Xorg do not require an xorg.conf. Your graphics card and monitor are auto-detected and set up automatically. This is why xrandr is used now.
If you install the nvidia driver though the driver creates an xorg.conf in my experience.
You can just create an xorg.conf in /etc/X11 and add what you want to it and Ubuntu should (hopefully) use your settings accordingly like previous versions of xorg did.
