Screen Resolution problem on Dell laptop

[ahmadonly]

Dear friends,

I am new user of Linux, i have just installed Suse 10 on my dell inspiron 6400 laptop. everything is going very fine, but i couldn't manage to increase the screen resolution from 800x600 to higher resolutions, i have tried Yast and tried to increase the value from there, but it doesn't work in increasing the resolution

please tell me how to do it.

thanks

Hi and Welcome !

Execute this in Terminal / Konsole :

su -
lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

Post output here.

Dear friend, following is the output of the code you have told me
============================
linux:~ # su -
linux:~ # lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Mobile Integrated Graphics Controller (rev 03)
linux:~ # grep -i driver /etc/X11/xorg.conf
Driver "kbd"
Driver "synaptics"
Driver "mouse"
Driver "fbdev"

Log in as root user and open /etc/X11/xorg.conf in any Text Editor. Replace Driver "fbdev" with "intel". Save file and reboot machine. In case it doesn't work, try Driver "vesa".

dear friend, i have changed the fbdev with intel, but what happened that next time i logged on the GUI doesn't start and it gives the message that "intel" is not recognized.
Now what is the method to recover the old value in the file by editing it without going in the GUI. because i am not familiar with the command prompt of linux. i tried to open the file by using the dos commands i remembered, but it didn't work. please guide me. and tell me that after recovering what should i do next to solve the issue. because i really love to use linux.

I think that joe is installed by default. Joe is a nice simple text editor.

So log on as root

type

joe /etc/X11/xorg.conf

Try the vesa driver it is THE generic driver.

Note it is always good to make a backup when modifying config files.

You can move to the directory by

cd /etc/X11

Just like DOS

Edit xorg.conf file as suggested by gogalthorp and replace intel with vesa. In case it doesn't work, post the Device VideoCard section of xrog.conf file here.

Thanks dear friends, your suggestions have worked and "vesa" is configured, the resolution has also increased now. thanks for that.

but a new thing i have discovered that from YAST when i try to open "Graphic card and Monitor" icon, it doesn't open, it gives response on click but doesn't open any configuration window after that. before recent changes it was working.

Post the contents of /etc/X11/xorg.conf file here.
