Unichrome DRI

**Gullible Jones** · 09-02-2005

Well, my old machine got fried by lightning, and now I have a new one, with Unichrome onboard graphics instead of Prosavage trash... But I'm still having trouble with DRI.

You see, I went to dri.freedesktop.org/snapshots and downloaded the latest "common" and "via" snapshots, decompressed them to /root/dripkg, and ran the install script (from the command line, with X turned off, of course). When I tried starting X again following the installation, though, my monitor immediately went into what appeared to be power-save mode. Turning off DPMS support, both in xorg.conf and the BIOS, did not solve the problem, and I was forced to reinstall X and the kernel.

Could someone please tell me what's going on? Is there something I must enable or disable in order for DRI to do anything?

Okay, the problem turned out to be simple enough: the X driver from the DRI snapshots was different from the one from unichrome.sf.net. So I've downloaded and compiled XOrg 6.8.2 as per the unichrome.sf.net instructions, and have the Unichrome stuff on my HD...

But, I've just found out that VIA has proprietary drivers available for download (in RPM format) in the drivers section of viaarena.com! Anyone know how good these drivers are?
