I have HP 6710s laptop with slackware 12.0 (kernel 2.6.22.9, xserver 1.3.0- slack 12 default) and I have troubles with glx. With slackware 12.0 default driver - xf86-video-intel-2.0.0 there is DRI but colors looks terrible - there are visible lines on color gradient patterns. With driver provided in slackware distribution in directory /patches - xf86-video-intel-2.1.0 colors OK, DRI working, but when I test with GL screensaver X server lockups with something for insufficient free memory to allocate in logs I don't have these logs now. I've downloaded the latest intel drivers from <a class="moz-txt-link-freetext" href="http://www.intellinuxgraphics.org">http://www.intellinuxgraphics.org</a> and after compiling them I don't have DRI I got the following error in logs: (EE) AIGLX error: drmMap of framebuffer failed (Invalid argument)(EE) AIGLX: reverting to software rendering and the following warnings (if it's helpful): (WW) intel(0): Removed DRI frontbuffer mapping in compatibility mode. (WW) intel(0): DRIGetDeviceInfo will report incorrect frontbuffer handle. So I can't get my videocard working properly with any drivers, please help whith any ideas or patches, etc. Thanks in advance! Best Regards, Svetlana </pre> </body> </html>
