Packard Bell laptop LCD resolution


I've installed Debian (dual boot with XP) on a Packard Bell Easynote lap. I find I cannot get a resolution of higher than 800X600. I believe it uses the Intel 82852/55 GM/GME chipset and I'm able to get high resolutions under windows. I searched around and read a lot of stuff about Xfree but it's all a bit technical for me and I'm afraid of screwing the whole thing up.

During the Debian installation I recall accepting a default of Vesa for the monitor. Was this wrong? Can I go back and run hardware detection again or fix the problem some other way.

Many thanks

You could probably use the i810 driver instead of the VESA one.

The file to edit is /etc/X11/XF86Config-4, look for "vesa" after the header Section "Device" and change it for "i810". It should look something like this:

Code:
Section "Device"
	Identifier	"Generic Video Card"
	Driver		"i810"
EndSection
Then, look for Section "Screen" under there, and edit it so that it looks like this:

Code:
Section "Screen"
	Identifier	"Default Screen"
	Device		"Generic Video Card"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		16
		Modes		"1280x1024" "1280x1024" "800x600"
	EndSubSection
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1280x1024" "800x600"
	EndSubSection
EndSection
This will provide a default resolution of 1280x1024 @ 24 bits (from DefaultDepth, and then it takes the first resolution). You can add higher/lower resolutions, the first one listed will be the one the X server will use by default, the rest will be available for you to switch.

Espero que sirva... ;-)

Cheers! (or should I say Salud!?)

Thanks or should I say "merci"!

Anyway, I did as you suggested and I got an X11 error at boot and got dumped at the command prompt. I added the lines that I commented out in the XF86Config-4 file leaving your suggested changes. I now have the following:

Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1280x1024" "1280x1024" "800x600"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1280x1024" "800x600"
EndSubSection
EndSection

I have lost the flickering I had before but I am still only offered 640X480 or 800X600. Any ideas?

Thanks again.

Do you still get that error message? Can you post it? The important part will be the lines that begin with (EE) or (WW), and the ones immediately above them.

I don't see any commented lines, but anyways, I think that the error is my mistake... The problematic line is this one:
Code:
Depth 24
		Modes		"1280x1024" "1280x1024" "800x600"
Probably your laptop (as mine) is not capable of showing 1280x1024, but perhaps the max resolution is 1024x768... So that line should read:
Code:
Depth 24
		Modes		"1024x768" "800x600"
Hope this helps!
