    Question Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I have an Intel 965 chipset. I have never had any freezes or problems with movie playback, and I get a consistent 680~740 FPS in glxgears with smooth animation. This is with the driver blacklisted.

    The only trouble is some "trailing ghost" effects during drag n' drop, and occasional graphical corruption in the form of multiple black outlines and a brief pause when minimizing a window.

    Should I try un-blacklisting the the driver to allow compiz, since everything else is basically okay? Or should I just leave it be?

    Cards are blacklisted if they exhibit crashes or problems with compiz using EXA & DRI1 - however, they have not yet been tested with DRI2 (which is enabled when UXA is active, and will be the default in the 2.8 intel driver). Therefore it is possible that compiz will now work without the problems experienced in DRI1, but in reality it could be even more unstable.

    Give it a shot, but be prepared to encounter problems (such as freezes during login - you'll need to switch to vesa in that case). If you're not experienced at fixing a broken X configuration, don't un-blacklist the driver in compiz.

    I've build the karmic 2.6.30-rc8 kernel for jaunty, using the sickboy config as a starting point. I've included the mtrr combining fixes, and enabled KMS. The only problems I have now is degraded graphics performance after a few hours (glblur goes down from 20fps to 11fps) and suspending with /home mounted on a sdcard - even with sickboy's options I now end up getting corruption in /home.
    I built the kernel with this guide - - but using karmic's repository (so the git clone line should read "git clone git://kernel.ubuntu.com/ubuntu/ubuntu-karmic.git source"), and I had a couple of problems because of options that are set in regular configs and not sickboy; check my (jbernardo) comments on the end of that guide.
    With that kernel and the xorg-edgers ppa everything now seems snappier, and I can almost use google earth on my aspire... KDE4 with all efects (including the cube, blur, etc.) is smooth and responsive. And since I used sickboy's config, my boot time is around 20secs.

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Hi there,

    I was using the optimal configuration, but instead of using the provided kernel I compiled my own 2.6.29.4, and I applied the linux PHC and tuxonice patches and enabling KMS

    Performance was fine but, with UXA enabled, gdm would always crash after resuming. I tried different kernel versions, always the same problem. At the end, I tried installing the xorg-edgers packages and now alls is fine!

    Tuxonice works beautifully, UXA is enabled, kms gives me nice terminals and usplash and performance is also very nice.

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I've searched this thread and have not seen a discussion on a problem I am having updating to 9.04 on my Dell 700m w/ Inel 855gm video card.
    Install upgade from 8.10 goes fine and OS boots fine. the problem is the display comes up with a 1" black border on each side of the display. Trying to change r3esolutions does not help.
    I am quite new to Ubuntu, but am loving it, and don't really want to go back to the "W" world.
    Has anyone else experienced this video problem and found a solution?

    Thank you for your time

    Thanks for this - Safe Configuration works a treat for me with my 945GM. I have enabled tiling, by the way, and all seems to be well.

    Just a note for KDE users - add:
    Code:
    /usr/local/bin/fixmtrr.sh
    to the end of /etc/kde4/kdm/Xsetup.
    This runs as root, just before the login screen appears, so you don't need to manually run the script or put it in your autostart.

    The font corruption bug is known (as well as UXA crashing when Firefox displays large images), and it seems to be fixed upstream.
    If it's already fixed, then I won't be reporting it as a bug


    For the other folks affected, I fixed the missing terminals on CTRL-ALT-F2 etc by removing "VGA=791" (or something like that) from the main option in /boot/grub/menu.lst (ie the default one, which for me is now rc8, but I had that problem with .29 as well). The rest of the line is fine, just that last VGA bit.

    One thing I've noticed with that is that music stops when I switch to a terminal - previously, that didn't happen. Is that a setting I could tweak somewhere? In theory, my graphical session should still have access to the sound card while I'm in a terminal, no?

    Equally, note I've had no font corruption with bleeding-edge stuff. I was prepared to live with it, but it kept coming faster and faster after starting X (to the point where firefox would be unusable within a half-hour after logging in) so I bit the bullet and tried the bleeding edge configuration suggested. This was yesterday - had no issues so far. (fingers crossed!)

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Hello guys, just like thegrek and psycke83, Ive found myself struggling with the same big issue on my acer aspire one 110-ab (Intel chipset 945). I followed all the instructions and all the posts suggested,but nothing changed. Everytime I launch the script fixmtrr, I still have the same response: reg00: base=0x0fffe0000 ( 4095MB), size= 128KB, count=1: write-protect reg01: base=0x0fffc0000 ( 4095MB), size= 128KB, count=1: uncachable reg02: base=0x000000000 ( 0MB), size= 512MB, count=1: write-back reg03: base=0x020000000 ( 512MB), size= 512MB, count=1: write-back reg04: base=0x03f800000 ( 1016MB), size= 8MB, count=1: uncachable reg05: base=0x03f600000 ( 1014MB), size= 2MB, count=1: uncachable reg06: base=0x03f500000 ( 1013MB), size= 1MB, count=1: uncachable reg07: base=0x000000000 ( 0MB), size= 128KB, count=1: uncachable every help would be much appreciated. I love ubuntu, it works like a charm on my aspire one (512mb ram is not a lot, but this damn problem with playing flash video is really annoying! Anyway, thanx for your attention .

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    I just did a fresh install of Jaunty.

    Updated it with official repos and it's running as good, and fast, if not faster, than hardy did(I haven't tried compiz though)

    I've been on it all day and I've had no problems with garbled fonts or anything like that.

    I regularly take glxgears readings although some people will say don't.

    Code:
    hardy heron :
    
    1559 frames in 5.0 seconds = 311.707 FPS
    1748 frames in 5.0 seconds = 349.442 FPS
    1778 frames in 5.0 seconds = 355.596 FPS
    
    jaunty fresh install default kernel and default intel
    
    1642 frames in 5.0 seconds = 328.380 FPS
    1643 frames in 5.0 seconds = 328.480 FPS
    1576 frames in 5.0 seconds = 315.115 FPS
    btw my chip is i845g

    hope this helps someone else



    These are some older readings on Arch and Ubuntu:
    Code:
    Arch:
    415 frames in 5.0 seconds = 82.828 FPS
    429 frames in 5.0 seconds = 85.618 FPS
    425 frames in 5.0 seconds = 84.992 FPS
    Ubuntu:
    828 frames in 5.0 seconds = 165.505 FPS
    864 frames in 5.0 seconds = 172.673 FPS
    795 frames in 5.0 seconds = 158.900 FPS
    btw ..... I should mention I couldn't get the LiveCD to work.. so I choose the install Ubuntu option from the LiveCd menu
