fbdev on top of efifb or something similar or a native driver.

driver?


I don't know of such a list.  Possibly one existed when that man page 
was written.



Secondly, in more general terms, how likely is it to find Laptops
(especially), or PC/monitor combinations which are NOT
VESA-compatible?


Right now, the odds of that are close to zero.

Why do you ask?

 Why do you ask?

Thank you for your answer: this is perfectly fine for me.

I ask because I am doing a custom LiveCD with a software demo, which
as part of the show, should also work on a machine I will not have
access to until the actual event.
By targeting VESA I am hoping to therefore reduce the risk of an
unpleasant surprise at runtime.

This UEFI transition seems bad news.. I guess it will be more
difficult for these use cases in the future.

Thanks,

C.

vesa_drv compatibility question

2012-07-22 Thread soul
Hello,

I have a two part question about vesa and the xf86-video-vesa driver (vesa_drv).

First, I found mentioned in the vesa (4) manpage:


SUPPORTED HARDWARE
   The vesa driver supports most VESA-compatible video cards.   There  are
   some known exceptions, and those should be listed here.


Is there a list of such known exceptions? That is, VESA-compatible
cards which are known NOT to work at all or well enough with this
driver?

Secondly, in more general terms, how likely is it to find Laptops
(especially), or PC/monitor combinations which are NOT
VESA-compatible?
In other words, assuming a perfect VESA driver, how many x86 / AMD-64
laptop or PC users can be reached by targeting the VESA standard?

Thank you,

C.
