[Openchrome-users] Can´t get 1920x1200 with 24/16bit, on Samsung 2443 LCD, to work with openchrome on thinstation

[Petry Roman, SHS-S IT-TS]

Hello and first i have to say sorry for the big mail yesterday. Will zip it the next time..

Today i found an "option" which gets me to my resolution. I had to enable

	        Option     "VBEModes"           "true"

Is there a cause in the x.org.log which explains why i have to use this ?

Thanks
roman

	Hello
	i?m facing a problem with a new LCD on our Thinclients. We use Thinstation as our linux distribution . It uses Xorg7 and openchrome latest as driver
	I searched a lot and talked to some devs but can?t find a solution so far. The native resolution of this samsung is 1920x1200 and i get it to work, but the colors of the background images is not ok. I think it displays only 256 colors. I use the same logo as a spash screen for kernel booting and it get displayed at 1920x1080 without an issue.. Also if i enable vesa driver instead of openchrome 1920x1200 is working with 24bit colors..  Card gets detected as :Detected VIA VT3344 (VM800) - EPIA EN. Card-Ids (1106|3344)


	I hope somebody can drive me in the right direction..
	Here comes the x.org.log.. I enabled loglevel 6 and will attach also the x.config-0 which gets generated from thinstation..

	And here the x.config-0

	I changed the modelines and the parameters , the depth settings and so on.. Also gave the card 64 mb shared mem instead of 32.. No changes..

	Any comments are welcome..
	thanks
	Bye
