Re: [Bug 252094] Re: [i965, etc.] Poor graphics performance on Intel
VERY interesting. I am going to try this on my laptop tonight. What is the procedure to fail back if the new driver has issues? Just remove the backports repo, and reinstall original xserver-xorg-video-intel from the main repo?

Quote: "i try the vesa-mode: it works much better like the unstable intel-driver. the frames are lower but the window's are not longer ugly and confused. i load the xorg.conf.failsafe in the x11 folder. " This is interesting. How exactly do you force it to use the vesa driver ranther than the Intel driver since the xorg.conf file is no longer used in Intrepid? Back in day I would just change the ¨Driver¨ section to ¨vesa¨, but since this new Xorg doesn´t use the config file I´m not sure. I do not have a xorg.conf.failsafe file in the x11 folder. -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 252094] Re: Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10
I have the same xorg.conf as "the designer" does. Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection Basically blank. I know Ubuntu changed how X works in 8.10 w/ no config file, but I don't fully understand it yet. I'm so used to the old way, and at this point, I think I may prefer it. Can anyone explain it?

I grabbed a vid w/ my camera and uploaded it. It should be available shortly. The video shows exactly what happens when I try to start Ubuntu using the normal Kernel. The screen flashes all crazy, and then just sits there. I have to boot using "Recovery Mode" to get into a working X. http://www.youtube.com/watch?v=U0fHvWsWKtQ -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks. I was pretty sure I was using the Intel driver since i was able to turn compiz on. Is there a way to get a screen capture of the boot process other than recording w/ my camera? -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thats what I was thinking but am not sure. I've attached my Xorg.0.log. Either way, as you can see in the screencast, I have the same issues as a lot of other people. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/19787326/Xorg.0.log -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 252094] Re: Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10
I have this issue on my Dell Inspiron 1525 as well. I have a few other graphical issues w/ this Intel card as well. Marcelo above me had a good idea about the screencast. I'm adding mine, and it shows a similar experience. http://www.youtube.com/watch?v=UT8x_PGRolU Here is my lspci: [EMAIL PROTECTED]:/var/log$ lspci -vn |grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 0c) The other issue I have is that when I boot the machine from cold, or restart it, X will NOT load. If flashes a black screen, and then garbage, and then black, and then black. I see the hard drive light blinking so I know its actually loading in the background. I can press ctrl-alt-backspace, and then ctrl-alt-delete to get the machine restarted. I have to choose "Recovery Mode" in Grub, then choose the "Resume" option. Doing it this way, X will load fine, but performance is terrible.. but it's all I got! I can reproduce this every time I boot from cold, or restart the computer. -- Poor graphics performance and rendering errors on Intel GM965 system, Ubuntu 8.10 https://bugs.launchpad.net/bugs/252094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
