I found some more problems, if I open an image in GIMP and try to pan around using the space bar and moving the mouse, the mouse tries to move and come back in place or some pixels away and after about 5 seconds X crashes with this backtrace: Backtrace: 0: /usr/bin/X(xorg_backtrace+0x33) [0x8104fbb] 1: /usr/bin/X(xf86SigHandler+0x75) [0x80bbdf4] 2: [0xffffe400] 3: /usr/bin/X [0x80f3d67] 4: /usr/bin/X [0x8115f79] 5: /usr/bin/X [0x813b412] 6: /usr/bin/X [0x81117a8] 7: /usr/bin/X(BlockHandler+0x3b) [0x8087569] 8: /usr/bin/X(WaitForSomething+0x1f2) [0x8103352] 9: /usr/bin/X(Dispatch+0x72) [0x808451b] 10: /usr/bin/X(main+0x44d) [0x806fdef] 11: /lib/libc.so.6(__libc_start_main+0xe0) [0xb7b51608] 12: /usr/bin/X [0x806f351] Fatal server error: Caught signal 11. Server aborting There's another problem, with the new driver/kernel I get a very *ODD* display problem, the left of my screen is okay while the more you look at the right of the screen, all the odd lines are darker than even lines, like if it was interlaced on one side of the screen, look at the pictures. <a href="http://ticpu.net:8080/~jerome/pics/?img=./stuff/2009-03-14_laptop_screen_left.jpg">http://ticpu.net:8080/~jerome/pics/?img=./stuff/2009-03-14_laptop_screen_left.jpg</a> <a href="http://ticpu.net:8080/~jerome/pics/?img=./stuff/2009-03-14_laptop_screen_right.jpg">http://ticpu.net:8080/~jerome/pics/?img=./stuff/2009-03-14_laptop_screen_right.jpg</a> <div class="gmail_quote">On Fri, Mar 13, 2009 at 5:58 PM, Jérôme Poulin <<a href="mailto:jeromepoulin@gmail.com">jeromepoulin@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I just updated my kernel to 2.6.29-rc8 to test the new KMS for the i915 driver, I know it's in test, since then, when I start X it creates 2 output. My laptop screen LVDS1 and DVI2 which is not connected but appears connected. Using xrandr to switch it off does not work [ xrandr --output DVI2 --off ] and it appears my screen changed to something around the 96dpi instead of maybe 120, or at least it appears to have reduced. Is it a known issue, any workaround? Here is what I have installed: kernel 2.6.29-rc8 with KMS enabled for i915 dri2proto 1.99.3 libdrm 2.4.5 mesa 7.3 xf86-video-intel 2.6.3 xorg-server 1.6.0 Xorg.0.log: <a href="http://dpaste.com/14185/" target="_blank">http://dpaste.com/14185/</a> xorg.conf: <a href="http://dpaste.com/14186/" target="_blank">http://dpaste.com/14186/</a> I'm aware of the warnings/errors about wacom, I just updated to xorg-server 1.6.0 and didn't recompile them yet. And now I have some cleanup to do, seems some arguments in the intel section are now invalid. Thank you for your help. Jérôme </blockquote></div>
