    Phoronix: Intel Comes Up With An Alternative To Bringing Back UMS

    The Intel Linux driver has been challenged by stability problems and other issues for owners of i8xx hardware since they rolled out kernel mode-setting and Graphics Execution Manager (GEM) support with UXA 2D acceleration more than a year ago. There were initial problems for other Intel users as well when switching to this overhauled driver stack -- to the point that it killed the netbook experience -- but those problems were quickly worked away. But for those using Intel's oldest supported hardware under Linux, the problems to this day remain. To circumvent this issue there's been the approach to add back user-space mode-setting to the Intel driver with EXA 2D acceleration to simply avoid these problems rather than correct the actual issues with KMS/GEM/UXA, but now another alternative has emerged...

    Also, Slackware was the only Linux distribution to try and help with the regression that shipped with the updated code. They included a few extra versions of the Intel driver for Xorg in Slackware 13.

    If only Linux distributions didn't make a big deal about sticking with their older products. You go to some of these websites and they never put up links off the main page for their older releases. It's always the latest.

    Your a idiot. Try going back to using pre-R200 ATI laptop devices in Linux (or any OS) and then maybe you'll have a clue why this is such a absurd statement.
    People buy what they can afford.

    Companies test their hardware with a version of Windows. With the 815 and 845GL's this would have been Windows 2000 or Windows XP. So if your computer came with that you should probably run that.

    BestBuy and Walmart don't sale Linux PC's. Until they do don't expect 110% from Linux. It's more the hardware companies and the Linux distribution's fault.

    Fedora and Ubuntu all knew there were problems with Intel's additions to the graphic code in Mesa, Xorg, and the Linux Kernel. They shipped distributions based on it anyway. People complained.

    What should have happened was that the parts that were added should have had versions of the software lacking the additions to compensate for the hardware which was problematic. Mesa and a kernel addition would have solved the problem. I blame Torvalds for this. He's always griping about crappy code and regressions and he let the largest 2 problems into the kernel. Graphics and Scheduling.


    Until we get a company guaranteeing their Linux distribution and supporting a package freeze beyond 6 months. Don't bank on linux.

    Because it was the latest kernel available when I filed the bug report (yes, one year has passed and it is still not fixed). I tried with 2.6.34 and 2.6.35 too, but it did not solved the problem.

    I don't have got intel mobile hardware, the desktop hardware (g33,q35,q45,h55+i5-680) did not have got this problem. I don't know of a Kanotix user with that problem too. But what i do not get is why you use 2.6.33.x kernel when 2.6.35 is stable, i even used 2.6.36 rc to test intel onboard. Maybe it is more easy to use those kernels with something differnet than gentoo

    my mome do have a i840 based p4 .. and yes its a shame

    the only you can do is install windowsXP... and after xp dies you can pull this hardware into the paperbox and use gasoline to burn the intel hardware.

    intel customers are just FAILING humans.

    For example:
    https://bugs.freedesktop.org/show_bug.cgi?id=27169
    https://bugs.freedesktop.org/show_bug.cgi?id=26664
    and much more minor bugs...

    I have to waste at least 10 minutes to boot and when kde is loaded it just *HANGS* the system when it detects when it detects the s-video out.
    xrandr didn't work too (with xorg-server >=1.8), I even don't know if it's already fixed.

    Which huge problems do you have got with gma 4500? You can not test h264 via vaapi but compiz / kde 4 effects should do.

    It's not because of i8xx, they just did too much wrong decisions concerning the development of the intel driver (like dropping ums too early).

    With the latest bits I still cannot use my gma45 properly.

    Well partly is a feature by design of Linux distributions... which is that to get an upgraded web browser, office suite, or even fix a driver you are expected to replace your entire stack. Yes you can get PPA's for some things, but running an older distribution (as a user) doesn't feel built in by design - if a user doesn't want to get into compiling code to make their new Wacom tablet work they will need to upgrade their distro.

    In this case, no your wrong.

    The Pre-GMA 8xx video devies sucked ass. I mean they were really really really really really bad. They never worked right and never were that stable in ANY operating system. They sucked in Windows, they sucked in Linux, they sucked in everything.

    OS X will never support them _at_all_. Windows Vista and Windows 7 will never support them properly and never did. Only XP works marginally better then Linux and even then it still is wretched.


    The fact that the driver authors are bothering to go back and try to update the support for these old and crappy devices _at_all_ to be compatible with the sweeping modernization efforts that have happened to Linux and X Winodws in the past decade goes to show that they actually do care about their users and backwards compatibility with hardware.

    I wouldn't. I owned 8xx devices and even worked with them professionally in embedded devices.... and I would not even give that much of a shit about it.

    If they actually get 8xx devices working with xrandr and all that, even with out hardware acceleration, this is still better then 8xx users ever had.


    OMG
    Next time I will buy an ati powered laptop instead...
