[Bug 56100] Re: regression: poor X11 performance on Dell Latitude D810

I'll close this now if you cannot debug it further. Reopen if you still see the issue with Feisty. ** Changed in: xorg (Ubuntu) Status: Unconfirmed = Rejected -- regression: poor X11 performance on Dell Latitude D810 https://bugs.launchpad.net/bugs/56100 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is probably my last update to this bug report as I am now running etch instead of dapper on my laptop and have 100% of desired functionality working. I prefer to be running debian but had been running Ubuntu since it installed and worked more easily in the past, but with this regression and the release of etch debian-installer b3, the balance has shifted. I would still be willing to help test fixes as long as I can do so by booting from a live CD image and installing fixes from there. On the vmware topic, having the video problem fixed helped a lot but not completely. A search on this determined that setting /sys/module/processor/parameters/max_cstate to 1 while running vmware was the rest of the problem. This is mainly for the benefit of someone who finds this bug report searching on google. I'm attaching my xorg.conf from my etch system. The only customizations I did on it from the xorg.conf generated by debian-installer were to comment out the synaptics stuff and to add dontzap. All the important display driver stuff is as detected. It seems like that the problem isn't with the xorg.conf though. -- regression: poor X11 performance on Dell Latitude D810 https://launchpad.net/bugs/56100 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I just tried installing Etch using debian-installer b3, and I have good X11 performance there too. Next time I have time, I'll try to figure out the differences. -- regression: poor X11 performance on Dell Latitude D810 https://launchpad.net/bugs/56100 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've done dpkg -P --force-depends xserver-xorg, rm /etc/X11/xorg.conf*, apt-get install xserver-xorg to get a completely default xorg.conf. I am attaching this here. This performance is only very slightly worse than what I get if I install the proprietary ATI drivers from ATI's web site using their ati-driver-installer-8.27.10-x86.run script. I run apt-get upgrade today and have dapper-security and dapper-updates in my apt.conf, so I should be up to date with respect to recent packages. My xserver-xorg is 7.0.0-0ubuntu45. My xserver-xorg-driver-ati is 1:6.5.7.3-0ubuntu7. My D810 has a 1280x800 display. lspci -v | grep ATI shows :01:00.0 VGA compatible controller: ATI Technologies Inc M22 [Radeon Mobility M300] (prog-if 00 [VGA]) I can provide additional information as needed. Just to be sure I'm not imagining things, I'm going to boot off of my old breezy live CD to make sure that X11 really does perform as I remember there. -- regression: poor X11 performance on Dell Latitude D810 https://launchpad.net/bugs/56100 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 56100] Re: regression: poor X11 performance on Dell Latitude D810
I am confirming that this X11 performance problem is not present when I boot off of breezy live. I snarfed the xorg.conf from the breezy live configuration and tried using it. I also tried using vga=771 which was necessary in breezy but not in badger. Neither of these things completely solved the problem, though it seems that loading GLCore instead of i2c might have sped things up a little. I'm attaching the xorg.conf from breezy for reference. Perhaps there was a regression between 6.8.2 and 7.0.0 of xorg? -- regression: poor X11 performance on Dell Latitude D810 https://launchpad.net/bugs/56100 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
