The difference is that framebuffer mapping is supported in xserver in newer version and intel driver uses this mapping. In the slackware 12.0 is useed DRI major version 5, minor version 0, Intel driver works properly with major version 5, minor version 4. With minor version 0 driver-intel tries to use it's own mapping that doesn't work. In slackware-current there isn't newer version of xserver so it must be built from source. -------- Original Message -------- <table border="0" cellpadding="0" cellspacing="0"> <tbody> <tr> <th align="right" nowrap="nowrap" valign="baseline">Subject: </th> <td>[Fwd: DRI and OpenGL problem with GM965]</td> </tr> <tr> <th align="right" nowrap="nowrap" valign="baseline">Date: </th> <td>Tue, 02 Oct 2007 20:21:30 +0300</td> </tr> <tr> <th align="right" nowrap="nowrap" valign="baseline">From: </th> <td>Svetlana Atanasova <a class="moz-txt-link-rfc2396E" href="mailto:svetlana@netissat.bg"><svetlana@netissat.bg></a></td> </tr> <tr> <th align="right" nowrap="nowrap" valign="baseline">To: </th> <td><a class="moz-txt-link-abbreviated" href="mailto:xorg@lists.freedesktop.org">xorg@lists.freedesktop.org</a></td> </tr> </tbody> </table> <meta content="text/html;charset=windows-1251" http-equiv="Content-Type"> <title></title> Hello again, I have found in google topic for similar problem but with nvidia drivers <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/archives/nouveau/2007-August/000247.html">http://lists.freedesktop.org/archives/nouveau/2007-August/000247.html</a> It's a problem with memory allocation My strace glxinfo returns the following error: mmap2(NULL, 6553600, PROT_READ|PROT_WRITE, MAP_SHARED, 4, 0xd0000) = -1 EINVAL (Invalid argument) fstat64(4, {st_mode=S_IFCHR|0666, st_rdev=makedev(226, 0), ...}) = 0 fstat64(4, {st_mode=S_IFCHR|0666, st_rdev=makedev(226, 0), ...}) = 0 close(4) = 0 write(2, "libGL error: drmMap of framebuff"..., 61libGL error: drmMap of framebuffer failed (Invalid argument) ) = 61 write(2, "libGL error: reverting to (slow)"..., 52libGL error: reverting to (slow) indirect rendering ) = 52 I have found this patch for nvidia: <a class="moz-txt-link-freetext" href="http://bugs.freedesktop.org/attachment.cgi?id=11070&action=view">http://bugs.freedesktop.org/attachment.cgi?id=11070&action=view</a> I want to adapt this patch for intel to resolve at last this memory conflict issue.

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>
