yet another SiS 740 question...

[aj2004]

I have asked about his before... a year ago or so. I have an L7SOM mobo with an onboard SiS740 AGP video card. While configuring kernel 2.6.6 for compilation, I noticed that there was an option for 'Support for SiS chipsets (300, 315...etc)' and also 'acceleration for sis chipsets'. Because I have been wanting my video card to actually have even a little acceleration, I was pretty giddy when I saw this, so I obviously checked it. While compiling, I noticed that, for the sis module, it was named 'fbsis'. So, I rebooted my machine into my somewhat troublesome new kernel (my old one, 2.4.22, was running too slow to do anything with), I started X/KDE and tested my video card on an openGL screensaver. There was no screensaver because my video card isn't accelerated. I then remembered that the module was compiled as 'fbsis' instead of the generic sis chipset, which is just 'sis'. I went into the X config file and changed the driver to 'fbsis'... this did not help at all. I checked my X log file, and it states that there is no DRI support for my card either.

soooooo, my question is... and I know this gets asked a lot... but, is there a way to get the SiS 740 onboard AGP video card to work with openGL in Linux? It worked pretty good running under Window$(which corrupted my 80gb HDD... Microsoft will _NEVER_ come near my computer again). I was able to play RTCW:Enemy Territory just fine (although gfx were turned to min). This would most likely be the only thing (other than maybe WINE) that I don't have working properly... _IF_ I had the courage to install windows again, having my video card working with acceleration would be the only reason for doing so.

I have read the numerous comments that "SiS ..., ..., 740/315, etc. chipsets are NOT supported by DRI or OpenGL", so, I have done a slight amount of reading... and, instead of flaming me for asking this question, ignore it instead if you think I am a retard (which I am)

I just posted the first link in the SiS 315E thread. See if it helps along with these other two on SiS and X config options.

sorry, but that wasn't much help. About all I found out was that I am supposed to use the "sis" driver, and it's supposed to give me acceleration. Just how much acceleration is one supposed to obtain? I am using X v.4.3.0 Feb 2003. On the X website, they state that the 650/740 chipset is supported and accelerated. Maybe it's accelerated but not able to do OpenGL? If so, then what's the point of acceleration. Even some regular, non-OpenGL screensavers run choppy on my computer.

One other thing: I don't know if it's just because my computer is constantly being fiddled around with (hardware-wise) or if SiS just makes video cards that deteriorate quickly... or if it's my monitor (10 yr. old HP-A4033A 21") but when I run a resolution of 1024x768 or 800x600 @24bpp (probably other colours too), I get this glitchy screen. It will suddenly cut out and then re-appear, the cut out... and it does this probably once every 3 seconds or so... and it doesn't stop. I know to never use an onboard video card if I can help it... next time I'm going with a mainstream, well-supported card (ATI or NVidia).
