I'm having a problem with a program I wrote using OpenSceneGraph and OpneGL. The program builds a 3D tree of arrows with n branches from each parent branch and m levels of branching. Note: what I call a branch, other often call a subtree. Birds don't sit on subtrees, they sit on branches. When I build the tree with more than 3 levels of branching, it locks up then either fails like a nice application and gives me back my display, or locks up various subsystems sometimes to the point where the only option is the on/off I/O device, i.e., can't ssh in. The program runs fine on XP. On SuSE 9.2, running on the same box, I receive the following errors: "Warning... Video Sync not working correctly" (from Producer) and "radeonWaitIrq: drmRadeonIrqWait: -16" from who knows. One suggestion I received was that I might have something from Mesa installed that I don't need. Is there such thing as a Mesa video driver that could be substituted with an ATI driver? Here's all the relevant configuration info I can think of. The box is a P4 2.4 with an intel MB, and a gig of RAM. Not that the fglrx README does not specifically name my hardware as supported, but the problem happens whether that is installed or not. Any suggestions as to what I might to to fix this? ljosalfr:~ # hwinfo --gfxcard 18: PCI(AGP) 100.0: 0300 VGA compatible controller (VGA) [Created at pci.273] Unique ID: VCu0.G_wQWNYi3c6 Parent ID: vSkL.HMrCSWFGDg0 SysFS ID: /devices/pci0000:00/0000:00:01.0/0000:01:00.0 SysFS BusID: 0000:01:00.0 Hardware Class: graphics card Model: "PC Partner RV100 QY [Sapphire Radeon VE 7000]" Vendor: pci 0x1002 "ATI Technologies Inc" Device: pci 0x5159 "Radeon VE" SubVendor: pci 0x174b "PC Partner Limited" SubDevice: pci 0x7112 "RV100 QY [Sapphire Radeon VE 7000]" Driver: "radeon" Memory Range: 0xd0000000-0xd7ffffff (rw,prefetchable) I/O Ports: 0xc800-0xc8ff (rw) Memory Range: 0xff8f0000-0xff8fffff (rw,non-prefetchable) Memory Range: 0xff8c0000-0xff8dffff (ro,prefetchable,disabled) IRQ: 11 (234010 events) I/O Ports: 0x3c0-0x3df (rw) Driver Info #0: XFree86 v4 Server Module: radeon Driver Info #1: XFree86 v4 Server Module: radeon 3D Support: yes Color Depths: 16 Extensions: dri Options: Config Status: cfg=yes, avail=yes, need=yes, active=unknown Attached to: #11 (PCI bridge) Primary display adapter: #18 ################################################################ ljosalfr:~ # 3Ddiag 3Ddiag version 0.722 Verifying 3D configuration: Using 3dinfo ************************************************************ Verifying 3D configuration for 3D board "ATI Technologies Inc Radeon VE (1002@5159)": Tests for X.Org configuration: Config File /etc/X11/XF86Config ... done.
