screen resolution 1600x1200 in ubuntu 9.10 HCL machine

Asked by Adnan Khan

Hii there

I have installed ubuntu 9.10 in my HCL system. In the System>Preferences>Display there are only two options 800*600 & 640*480.

Can anyone please tell me how can I achieve resolution higher to them like 1024x768 or higher.

These are the hardwares I have. Second last one i.e; 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 771/671 PCIE VGA Display Adapter (rev 10)
my graphics card.

In Administration>HARDWARE DRIVERS I have only ine option for Software Modem. None for the display card.
Under the Preferences>Display option it says UNKNOWN Monitor.

I came across this link

http://ubuntuway.wordpress.com/2009/07/13/drivers-de-sis-771671-para-jaunty but when i installed xorg-driver-sisimedia_0.9-1_i386.deb it made my system unstable & starts blurring the login screen & instead for asking password for login it showed command prompt like screen & asked my login & password there.

Please help me to make my system run nicely under higher resolutions

Thanks

Hi
First of all i would advise you not to install any software apart from those provided in the official repos and some PPA's you trust.
Secondly,please run jockey-gtk to install extra drivers for your card and read this bug report : https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-sis/+bug/301958

Oh and one more thing,if youre on 9.04 i would suggest trying out 9.10 and 10.04 to see if the issue is resolved

Try the following. Maybe it helps.

1: Copy the file /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak
2: In a Terminal enter sudo gedit /etc/X11/xorg.conf
3: Have a look at the screen section (the sub section is important)

Section "Screen"
 Identifier "Default Screen"
 Device "nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro]"
 Monitor "Generic Monitor"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800"
        EndSubSection
EndSection

4: Save the file
5: Restart the system

The update of the file shouldn't take more than 15 minutes – otherwise you're going to loose the root privileges and you wouldn't be able to save it.

Hope it helps.
Peter

@Adnan Khan Well press alt+F2 and type : jockey-gtk : and that will open up a new window asking for your password,enter your password and the program will search for any extra drivers that are needed to make the system work correctly,Activate any drivers you find and reboot

Hi
Did you check if this bug is fixed in 10.04? Also did you see the bug report i linked this answer to?

Revision history for this message
Adnan Khan (mailme-adnan89) said : 		#13

No I didn't checked in 10.04. I dont have the image for that.

And yes I saw that report. But i got nothing in that.

Rohan Garg (rohangarg) said : 		#14

Can you also check if you have xserver-xorg-video-sis installed? i believe that is the default graphics driver for Sis Cards

Revision history for this message
Adnan Khan (mailme-adnan89) said : 		#15

What are you saying to check me? on ubuntu 10.04?
