Note that I'm using gtk2-2.13.7-4.fc10.i386 with that fix in: https://www.redhat.com/archives/fedora-extras-commits/2008-August/msg05169.html I'm also seeing this - flickering at graphical login - and lots of "underrun on pipe B' messages. The only difference is I'm on x86_64 - a Vaio SZ3. 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) The desktop seems a little slower than normal and the font in the GDM login screen seems larger than before, implying a lower resolution.

I am not seeing any flicker on application startup, but I am seeing a 'glitch' or slight delay in redraw sometimes and it seems to wait until some input before redrawing. For instance when I login to gnome, I see the desktop background appear, but nothing else (mouse cursor spinner stops moving) until I move the mouse, then suddenly the desktop will redraw and menus will appear (mouse cursor spinner starts again). This happens every time I login (just a normal gnome session with metacity), and I've waited up to several minutes with this redraw hang then moved the mouse to have it instantly redraw; this is not just a matter of cpu load while starting up apps. It seems that applications opening new windows also do it very slowly right now, sometimes staying blank white for much longer than normally should. Also running intel GMA950, macbook 2,1, 2.16G c2d, rawhide fresh installed 20080912. I now suspect this is related to the synaptics touchpad driver, as I'm still seeing the problem on my laptop, but not on a desktop also running Rawhide. This is already fixed in the kernel. It was a regression with the modesetting code. Even when modesetting wasn't used, interrupts weren't enabled properly on the graphics card. Dave Airlie fixed this during Plumbers IIRC. |

This seems to only appear as new applications are launched. Something in the GNOME desktop might be probing the display for every started app though: (II) intel(0): EDID vendor "LCD", prod id 22754 (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1280x800"x0.0 72.10 1280 1296 1344 1448 800 802 804 830 -hsync -vsync (49.8 kHz) (II) intel(0): EDID vendor "LCD", prod id 22754 (EE) intel(0): underrun on pipe B!
