    Cleaning Up The Linux Graphics Driver Stack

    Phoronix: Cleaning Up The Linux Graphics Driver Stack

    Yesterday Luc Verhaegen gave a talk at FOSDEM on reverse engineering a motherboard BIOS, but today we finally have X@FOSDEM for the last time. Luc has just begun his talk on unifying and simplifying the free software desktop's graphics driver stack. Here are his slides and we will be back with more updates and videos on Phoronix as the presentation progresses.

    Too hot for TV or what?

    Anyone getting drop kicked through a window?

    I am very curious. It sounds to me like a real issue, this lack of being able to update display drivers in Linux, without affecting the whole system. I'd like to learn more about it.

    The cursor bug was solved through HwCursor = FALSE, like most things.

    The mis-detection of the screen is a very basic modesetting issue, due to the fact that there have been at least three different LCD modules shipped with this device.

    And i believe that the hardlock and the console corruption issues were related to the pci-express bus being partially disabled.

    At this point, openChrome is stable, so even if some of these bugs were related, that is still several bugs fixed. So yeah, I agree, not much development there.
    The only guy who does anything at openchrome is Bartosz (gang65). Everyone else is talking big but not doing anything.

    Now, the level of activity at openchrome is so low that it can be considered just as dead as unichrome (which sees more development still when i get round to it).

    Fedora, on the other hand, is NOT RHEL, though they may share developers.

    Again, I repeat my comment, WHICH distro had to lay of it's developers? Something tells me Red Hat are getting it right, and I can't help but suspect that ignoring the consumer desktop in RHEL is one of the things making a big difference.
    Do you really need me to repeat mine about novell being a bank? SuSE is no longer making a loss now that some big spenders have been shed. Sadly a lot of clued people had to be thrown out first due to corporate governance idiocy.

    It is, but not much code from that is flowing back. And it's been a while since there was any buzz there. Turns out, olpc is mostly using fb.
    It's still VIA hardware in recent machines, but as you say, no one cares about it, and it would spoil your claim that no one cares about VIA hardware if they did. The fact it uses FB mostly still doesn't stop it being VIA hardware people care about.

    Why are Red Hat going to waste time advertising a product that is, essentially, not theirs. Almost no one "buys" a desktop OS anymore, the Linux crowd all use whatever their chosen flavor of poison is, and the Windows and Mac crowd don't separate the OS cost from the computer itself.

    The applications I listed are both derived from old Unix workstation apps, which are going to mostly be sold on nice workstations shipping with 6 figure instruments. So Red Hat are not selling their desktop offering to the end-user, they are selling it to Bruker and Varian, and strangely enough, pretty websites are not going to make that much difference.

    Fedora, on the other hand, is NOT RHEL, though they may share developers.

    Also, isn't OLPC using a VIA graphics chip? Not that it counts, no one cares about OLPC anymore...

    This sounds a little strange given that Bruker specifically list RHEL as the only supported Linux distro for their Topspin Software. No mention of SUSE, nor Ubuntu. Varians MestRecNova software also only seems to mention RHEL as a supported Linux distro. Now I will freely conceded these are both A) specialized apps, and B) expensive, but they are also the only two apps worth mentioning in their field, so strange they bother supporting a distro that doesn't do desktops.

    It seems to me that Red Hat aren't very interested in pushing Linux desktops for home users, which isn't very surprising as their is no money there. Let us note which distro needed to do major layoffs...

    Ok, that's only one application, but it's the only field I really have the experience to point at that clearly and say "See, RH, no one else".
