card into a state where only the Linux OS can <br>communicate with it. At power on for example, there is no evidence of <br>video being generated hence the POST screen and BIOS setup are invisible :-(<br><br>I would like to reset the card back to factory defaults (apart from knowing <br>what caused it to get so distressed!)<br><br>System:<br>ASUS P5K motherboard<br>Sata drives (1 by 73GB system, 3 by 320GB in software RAID5)<br>4 GB memory<br>Intel 6600 Core 2 Duo CPU<br>openSUSE 10.3 for x86_64<br>nVidia GeForce 8500GT video card<br><br>The initial OS used was Ubuntu but for various reasons I wanted to use <br>openSuSE on this system. Installed 10.3 yesterday - sweet sailing. It <br>even passed across the three user accounts and their passwords, and <br>preserved the software RAID5 array. Colour me impressed.<br><br>Started tweaking the video -- this is a medical imaging workstation which <br>will run some fairly top-end software. GLUT dependant, some of it, so
had <br>to get Xgl on there. Followed some HOWTOs for installing/running Compix <br>on openSuSE and all went well until the configuration of the nVidia drivers.<br><br>At that point it overwrote the xorg.conf file (this was expected) but from <br>that point on things started to go pear shaped.<br><br>First hint of problems was the fact that after logging off one user and <br>preparing to log on again, there was just a black screen - no evidence of <br>video coming out of the video card. SSH'd into the box and replaced the <br>xorg.conf with a previous known-good copy. Restart X and we're happy <br>again. But no glxinfo, no glxgears, etc.<br><br>Then decided to do a power down and restart. It was then I noticed the <br>absence of video output during POST and OS startup. The first evidence of <br>video is the openSuSE signon screen. Cannot even get to an Alt-Fx <br>terminal. Yikes!<br><br>Several nvidia-xconfig and other xorg-related tweaks later, still
having <br>the same problems.<br><br>Latest nVidia driver from website (installed using YAST as per nVidia <br>instructions.) Have also located documents suggesting that YAST is *not* <br>the installation method of choice and I will explore that tomorrow.<br><br>But in the meantime I have an apparently "invisible" POST and BIOS setup <br>which is not comforting. Either the BIOS settings got changed during the <br>xorg tweaking (highly unlikely) or the nVidia card got itself reprogrammed <br>into a state that it does not function in any way unless driven by the <br>nVidia drivers and the Linux OS. Great, but not good for BIOS tweaks, <br>etc! And it still does not respond to glxinfo - claims it cannot see <br>display 0:0<br><br>So to return to the prime question, how to reset the card back to factory <br>defaults? Pref. using Linux :-) Or is there some other explanation - <br>and
fix?<br><br>TIA,.<br>Denis<br><br><br>_______________________________________________<br>PLUG discussion list: plug@plug.org.au<br>http://www.plug.org.au/mailman/listinfo/plug<br>Committee e-mail: committee@plug.linux.org.au<br></blockquote><br><p>
