Screen Resolution

man5237 · 10-12-2008, 02:59 AM

I installed Debian in my PC.
But the maximum possible screen resolution is 640X480

How can I increase the screen resolution?

My monitor is Samsung SyncMaster 763MB

the xorg.conf file in my PC is as follows

Code:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I edited the file according to this.

But Still now I am not able to change the resolution.

The only possible resolution now available is 640x480.

Hi.

[QUOTE=man5237;3307481]I installed Debian in my PC.
But the maximum possible screen resolution is 640X480

How can I increase the screen resolution?

So what I meant to say is the file /etc/X11/xorg.conf has be configured with refrence to your monitor.

Replace 640x480 by 1280 x 1024 - and hope all ends well.

BTW it would do you great help if you backup xorg.conf file.

man5237 · 10-13-2008, 09:12 PM

I replaced .But not working.

But still, the only available resolution is 640x480.

What can I do ?......

Hi there,

There is one more thing you can try. You have a 'i180' driver installed on the pc. Try changing that driver to 'vesa'. 'vesa' is a generic driver - think that will help.
Section "Device"
Identifier "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device"
Driver "i810"
BusID "PCI:0:2:0"

change this to
Section "Device"
Identifier "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device"
Driver "vesa"
BusID "PCI:0:2:0"

man5237 · 10-14-2008, 04:18 AM

that too tested.

But not working

honeybadger · 10-14-2008, 08:10 AM

Hi there,

I am sorry I was not looking at your graphic card
Though I am not very sure but I think you would be needing a 'vga' driver and not vesa

You can also run this command as a root
dpkg-reconfigure xserver-xorg

It will give you a change to rewrite xorg.conf.

Again, I am sorry for all the inconvinance I caused

man5237 · 10-14-2008, 10:28 AM

Sorry Dear .

Not working .

Changed driver to vesa and then to vga but not working.

if changed to vga graphic is not displaying.

So I changed that to 'i810'.

But cant change the resolution.

Any other way..

Hi there,

Sorry for the delay for the answer.

There is a similliar post at
http://www.linuxquestions.org/questi...roblems-69720/

but I think we have done all of it already.

Also I think that you can download the driver for your card http://downloadcenter.intel.com/Prod...D=865&lang=eng here and then check.

If this fails - can you please post again in a new thread?
