How to get more than 800x600 resolution in Xorg?

#1 Post by kitsumimaru »

Hello, I am a complete newbie to linux, and have installed (successfully) puppy 4 on my netbook.

Everything seems to work beautifully and I'm loving the ten second boot time!

(here comes the inevitable 'but')

But, I am having massive headaches enabling/installing my videocard.
I have trawled through the forums here but I am not at all savvy with half of the terminology used, and was wondering if anyone could (please!) help to guide me through this problem?


I have tried to follow some of the guides :
http://murga-linux.com/puppy/viewtopic. ... 3&start=15

This being the one which seemed to have the most answers, unfortunately I cannot download Kirk's pet so I cannot test whether it works, and am now utterly confused as to how to get my screen working in xorg at a resolution higher than 800x600

I'm currently using the vesa mode at 1024x600 and it looks spiffy, but the video playback looks very poor, pease help me!

Thankyou in advance,

Kit

xorg at a resolution higher than 800x600

I am in a similiar situation.
My mini-ITX Via VB7002G box has openchrome graphic chip.
Xorg resolution not higher than 1024x768
I use xvesa 1920x1080.

Until last week I have been thinking that unichrome is the bad guy.
But I have tried Xorg in another distro and there unichrome was working in 1920x1080, they use Xorg-7.5.

You should try Fluppy. It's a bugfixed Puppy4 with newer drivers, included an updated Xorg.

"exceeds panel dimensions" is a lie :oops:

From the comment in Barry's blog, this topic doesn't seem to be resolved yet: http://bkhome.org/blog/?viewDetailed=02197

Maybe this will help?

I have recently acquired an old 5.25" SBC with a VIA chipset. It seemed an ideal candidate for resurrection with Puppy. Sure enough, it all started up OK, but I could not get it to work at more than 640 x 480 resolution.
Googling didn't throw up anything useful, then I had a "Eureka!" moment...

The video on this particular board is part of the Northbridge chip, and essentially an "S3 Twister". It supports both LCD and CRT displays. The BIOS defaults to "CRT + LCD" but I am only using the CRT interface (15-pin D-type VGA connector) to an LCD monitor. The LCD interface is designed to drive an LCD panel directly.

Setting the BIOS to "CRT" (so disabling the LCD interface) magically allowed Puppy to run at the full 1280 x 1024 resolution of the monitor :)

Maybe this will work for someone else? I don't exactly understand why the LCD setting limited the resolution of the display; Xorg wizard offered all the resolutions, just that whatever was selected, it only displayed at 640 x 480...
