Hello, We recently bought a G450 eTV for 3D acceleration under X with dri. The G450 is claimed to be supported by DRI. We searched the mailing-list archive for a similar case, without success. It always works fine in 2D, it doesn't start if we include Load "glx" in XF86Config-4. The server catches signal 11 in (II) [GLX]: Calling GlxExtensionInit Misc info: - Card:Matrox Millennium G450: Matrox|Marvel G450 eTV [DISPLAY_VGA] - Mandrake 8.2, standard kernel Linux rio.lip6.fr 2.4.18-6mdksmp #1 SMP Fri Mar 15 01:24:36 CET 2002 i686 unknown - Biprocessor : Intel(R) Xeon(TM) CPU 1.50GHz - lspci output (mainly for chipset info) 00:00.0 Host bridge: Intel Corp. 82850 860 (Wombat) Chipset Host Bridge (MCH) (rev 04) 00:01.0 PCI bridge: Intel Corp. 82850 850 (Tehama) Chipset AGP Bridge (rev 04) 00:02.0 PCI bridge: Intel Corp. 82860 860 (Wombat) Chipset AGP Bridge (rev 04) 00:1e.0 PCI bridge: Intel Corp. 82820 820 (Camino 2) Chipset PCI (rev 04) 00:1f.0 ISA bridge: Intel Corp. 82820 820 (Camino 2) Chipset ISA Bridge (ICH2) (rev 04) 00:1f.1 IDE interface: Intel Corp. 82820 820 (Camino 2) Chipset IDE U100 (rev 04) 00:1f.2 USB Controller: Intel Corp. 82820 820 (Camino 2) Chipset USB (Hub A) (rev 04) 00:1f.3 SMBus: Intel Corp. 82820 820 (Camino 2) Chipset SMBus (rev 04) 00:1f.4 USB Controller: Intel Corp. 82820 820 (Camino 2) Chipset USB (Hub B) (rev 04) 00:1f.5 Multimedia audio controller: Intel Corp. 82820 820 (Camino 2) Chipset AC'97 Audio Controller (rev 04) 01:00.0 VGA compatible controller: Matrox Graphics, Inc.

(my G400 works just fine, tho). I haven't tried the latest binary drivers from Matrox; but I don't have a lot of faith in them, based on my past experience.

Thanks for the info. The hardware database on Mandrake Linux website says that G450 is "known", but no Matrox is rated better, and G400 worked very well in 3D, with open-source drivers. The problem is that saying "G450 supported" is ambiguous if the G450 eTV is so different. It is a very bad habit for a vendor to put a very similar name for two different products. > I haven't tried the latest binary drivers from Matrox; but I don't have= a > lot of faith in them, based on my past experience. Vendor's website says about G450 eTV support on Linux: "none planned". We stick to open-source drivers and, for the moment, disabled completely 3D/opengl for our G450, which is kind of dumb (we bought it for 3D, not even mentioning the video I/O feature we can forget). About closed source drivers: we tried some on our NVidia Geforce2 cards. Their performance in 3D is astonishing, especially in very high resolutions (e.g. 1400x1500). But then often the X server gets stuck with keyboard disabled so X needs to be killed from the network and restarted. Worse, it seems that the machine becomes unstable, which we can't accept (closed-source kernel module is evil). As a consequence, we shifted back to fully open-source 2D-only drivers. I fear that due to the increasing complexity of video hardware, it becomes more and more difficult to have proper open-source support without the manufacturer's participation (at least good docs). Anyway, next time we'll pay even more attention before buying. No clear, proven, good open-source driver ? =3D> Skip this vendor. Users report good stability and performance of a precise product with open source drivers =3D> We take. Finally, thank you everyone who participates in free software. --=20 St=E9phane Gourichon - Labo. d'Informatique de Paris 6 - AnimatLab http://animatlab.lip6.fr/ - philo du dimanche http://amphi-gouri.org/ |

Oddly enough, I have a G450, and I've never had any trouble with it. It doesn't like a 640x480 screen mode (but has no trouble with higher resolutions), but otherwise works fine. Ron Steinke |
