[opensuse-xorg] XOrg deadlock in a multi-threaded X app that works on FC/RHEL distributions
by Myrosia Dzikovska 25 Jun '12

25 Jun '12

I am trying to get a library (written by someone else) to run on OpenSuse 12.1; I am not an X developer, but I inherited it and need things to run. The library is tested and runs on FC13, RHEL 5 and SL6 without problems. But it consistently creates deadlocks in X calls on OpenSuse 12.1 The sequence of events is 1. XInitThreads is called 2. The library creates a thread ("XEventThread") and starts executing it. The thread executes a simple loop that repeatedly calls XNextEvent and passes the returned events elsewhere. 3. XEventThread calls XNextEvent 4. XNextEvent blocks waiting for events; it does not return immediately because there are no windows yet 5. XEventThread releases control to the main app thread 6. the main app thread calls XLockScreen 7 the main app thread starts creating windows 8. The first call to X functions, e.g. XCreateSimpleWindow, hangs This is with XSyncrhonize enabled; if it is disabled, a few X calls will succeed, but eventually something will hang forever. On the OSes that work (FC13, ScientificLinux 6) the difference is point 8 - the calls to X never lock, everything proceeds happily. It works with a variety of window managers. Why is there a difference on the OpenSuse, and what can I do about it? I am happy to file a bug report with Novell, too, if this appears to be a bug. I originally asked a version of this question on the general X list (well, it started less clearly defined), and got a suggestion that this may be a thread safety fix missing from OpenSuse XLib. http://lists.freedesktop.org/archives/xorg/2012-June/054726.html I also created a cut-down version of the library (in the attached file) that displays the behaviour. On FC13 and RHEL it creates 3 windows with 3-second intervals between them, and then waits forever. It succeeds every time. On OpenSuse 12.1 it freezes as soon as the thread starts, usually on the first call to XCreateSimpleWindow during the creation of the first window. It is not affected by a window manager - fails for all of them. To compile gcc -O2 -ansi -g -DXGRAFIX -I. -DUNIX -D_cplusplus -D_XOPEN_SOURCE=500 -D_REENTRANT -c -o HGraf.o HGraf.c gcc HGraf.o -lpthread -lm -lX11 -L/usr/X11R6/lib mv a.out HGrafTest to run ./HGrafTest Is this indeed an OpenSuse bug, or am I missing something about the program? Thanks, Myrosia

[opensuse-xorg] Huge problems with glamor since intel 2.19.0 driver switch in XOrg repo
by Dr. Ralf Czekalla 16 Jun '12

16 Jun '12

Since the switch to intel driver 2.19.0 a week ago or so, I have huge problems to start X now. I always get this error message during start-up: [ 40.415] (II) Loading /usr/lib64/xorg/modules/extensions/libdri2.so [ 40.451] (II) Module dri2: vendor="X.Org Foundation" [ 40.451] compiled for 1.12.2, module version = 1.2.0 [ 40.451] ABI class: X.Org Server Extension, version 6.0 [ 40.451] (II) Loading extension DRI2 [ 40.451] (II) LoadModule: "glamoregl" [ 40.470] (II) Loading /usr/lib64/xorg/modules/libglamoregl.so [ 41.442] (EE) Failed to load /usr/lib64/xorg/modules/libglamoregl.so: /usr/lib64/xorg/modules/libglamoregl.so: undefined symbol: _glapi_tls_Context [ 41.442] (II) UnloadModule: "glamoregl" [ 41.442] (II) Unloading glamoregl [ 41.442] (EE) Failed to load module "glamoregl" (loader failed, 7) ...

The latter offered some changes in glamor.conf to do the loading of libs in the right order (glamor before Mesa). I tried this but it didn't change the error message above.

[opensuse-xorg] Mesa/Gallium3D: enabling build flags for XvMC & VDPAU state trackers
by Tyler 15 Jun '12

15 Jun '12

Hi, Not sure if this is the appropriate list to write too -- I realize that Mesa falls outside of Xorg, though its heavily related to some of the xorg elements. Anyway, given the absence of /usr/lib64/libXvMCr600.so and /usr/lib64/vdpau/libvdpau_r600.so from the package provided by either the repos for 12.1 or factory, it appears that Mesa isn't being compiled with the build flags being enabled for the XvMC & VDPAU state trackers. Rather obviously (from my missing files mention above) I'm looking to use these features with the r600g driver for an AMD video adapter. The XvMC state tracker is strictly MPEG1/2 decode support. The VDPAU state tracker, as well, currently only supports MPEG1/2 decode, though (hopefully) this will eventually be extend to support other formats. While MPEG2 decode support might seem rather pedestrian to some, it is beneficial to many others (Example: the ATSC digital TV system uses MPEG2 formatting for channels streams). In addition, users of hardware supported by the r300g and nouveau drivers would also be able to make use of the state trackers. Is there any reason why mesa isn't being built with those features enabled ? Or, more to the point, could they be enabled for the mesa package in factory so that users can take advantage of them (if they so choose and/or is useful to them)?

[opensuse-xorg] Is i915 driver working on i915 chip (or Iany?) for anyone running 12.2B1?
by Felix Miata 08 Jun '12

I don't see an existing filed bug about this. 11.4 and 12.1 work fine @ 1600x1200 on i915 on same machine. Several lines with 915 show up in lsmod output, but without glamor I can't seem to find any way to not have Xorg use only FBDEV driver, either with current 3.4 desktop kernel or the 3.4rc2 one last installed 7 weeks ago.

Re: [opensuse-xorg] Corrupted icons after hibernation
by Michael Lashkevich 11 Apr '12

11 Apr '12

Scsijon, I have finally managed the problem by installing an unofficial build of the driver "xorg-x11-driver-video-intel" from the repository "home:scalpel4k". It seems that this repository contains the latest driver build from git, and there is no such problem with this driver. I believe the driver included into the official distribution is buggy and should be updated. As well as I know I am not the only person who experience such problems (see Bug 738398 on the Bugzilla, which was opened on 2011-12-23(!) as Major(!) and has not yet even been assigned!!!).

[opensuse-xorg] Corrupted icons after hibernation
by Michael Lashkevich 07 Apr '12

07 Apr '12

Dear All, I have encoundered a despairing fault, which appeared after upgrade to OpenSUSE 12.1 (from 11.4). After every hibernation/resume many icons on the panels and in applications, and some other GUI elements become black or transparent (invisible). I need to restart programs and kicker (I normally use KDE3, but the corruption in XFCE as well, but not in icons in other graphic elements) to get rid of it. My computer loads "i915" module and chooses xorg "intel" driver. I tried to use the noKMS mode ("i915.modeset=0"), but the "intellegacy" driver, which is compatible with noKMS, always crashes on some applications (like firefox and thunderbird). I tried many device options, but to no avail (except for "Shading" "on", but this option spoils video players and some GL applications). Upgrade to "X11:/Xorg" packets produce no effect. Recently, I installed an older "xorg-x11-driver-video-intel" from "home:aevseev" repository. It helped for the first several hibernations, but then the problem returned. I have been using (Open)SUSE since 9.3, but have never faced such a problem. Can anybody help me?

Hello, On a fresh os-11.4 installation, my GeForce 7300 GS is driven by the nouveau driver. Unfortunately this driver is buggy: https://bugs.freedesktop.org/show_bug.cgi?id=36090 Is it possible to use an other driver for this card, and if yes, how?
