screen resolution

[Caveageman]

just installed Ubuntu hardy on to a laptop and only one of the screen resolutions works. and i can only see the top corner of the desktop. all the other resolutions just give me fuzz. can any one help me?

Hit alt+F2 and type "displayconfig-gtk" (without the quotes), select your monitor and then your correct resolution. If you have an Nvidia card then again and type "gksudo nvidia-settings" (again without the quotes) and hit "Save to X Configuration File", restart and you should be OK.

Thank you but i dont know if i have a nvidia card and that second conmand doesnt do anything just back to the command line and the first one goes to a window thing i can select a resolution and click test its fine click ok and nothing happens just dissapears back to the desktop. thanks again

You should log out and log back in for changes to take effect.

i think you should find out what graphic card you are using by typing

lspci
in terminal.

If you have problems to open a terminal, just switch away from your x-environment by typing

Strg-Alt-F2
then log in.

the result should look like:

00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1)
00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01)
00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01)
00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01)
01:00.0 VGA compatible controller: nVidia Corporation GeForce 8400 GS (rev a1)
02:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8110SC/8169SC Gigabit Ethernet (rev 10)


you can see it says "VGA compatible controller: nVidia Corporation GeForce 8400 GS", look for something similar.

Or post your result here

Hey,

i think in this thread you´re going to find the solution for your resolution ;-)

[URL="http://forum.ubuntuusers.de/topic/165210/?p=1336088#1336088"]

good luck!

EDIT:
Oh, sorry, i didn´t realize it is in german language...
you don´t understand german? do you?

[adieb]

so here a possible solution in english:


remove unwanted drivers:

sudo apt-get -f remove xserver-xorg-video-openchrome xserver-xorg-video-unichrome


edit your xserver-config:

sudo gedit /etc/X11/xorg.conf

go to section "device" an change Driver "vesa" to Driver "via" + add two lines. it should look like this:

Section "Device"
Identifier "VIA Technologies"
Driver "via"
BusID "PCI:1:0:0"
Option "VBEModes" "true"
Option "EnableAGPDMA"
EndSection

Save the file and restart your X-Server by:

Strg-Alt-Backspace

to check if your driver is working type:

glxinfo | grep direct

when it says "Direct rendering = yes" it worked
