This was a problem with Xfree , it happened in Linux also, i think it was not saving the text video screen properly, or something like that. sorry, i had to reboot to get out of this problem.

The timings that I sent work with my NEC SVGA monitor. They might work with other NEC monitors as well. I cannot validate this. I notified fred@lepanto.mwc.com of my posting so that the message doesn't sit at the bottom of a heap of other mail messages. Unfortunately, I don't currently have them, so I am unable to post the timings. I derived the timings by following the instructions that MWC posted. The instructions are also in /usr/X11/doc for those with 4.2/X. I'm happy to say that the timings that I derived work. If MWC hasn't posted what I sent to them by tomorrow, I will post them myself. Keep in mind that the timings may not work if you have a different monitor. However, I have a SVGA monitor, so if your monitor is SVGA-compatible then they should work. Good luck!

Keywords: ati, oak, vga2, Xwindows Summary: vga card doesn't cooperate in X I'd hate to post so many newbie questions, but I feel cornered... Tried to hook up X under Coh 4.2 again last night. No good. I called MWC support, and the guy on the other end went through the standard questions.. RAM? Resolution? Number of disks installed from the X package? I finally forwarded my Xconfig and the nohup.out Well the final verdict was that the oak card was no good. I asked if there was any card that was recommended as compatible now, and useful for future releases. ATI "mach 32" cards wre the answer. After fussing around with files for a while longer I ran out to the store and _bought_ this (300.00) card. Just had to see if I could get X to run (it crashes). Well I reached a point where it _might_ not crash totally, just halt stuff for a while. The message back would be about trying to get X up, after 70 of so trys, and failing. It varies a bit though, sometimes the system doesn't come back, so I reboot. Also, the autodetect did not like the ati Graphics Ultra+, this caused the system to lock as well (so I reinstalled). Question(s): If the Oak is so bad (is it?) what's a safe bet card (under $300.00)? I'd replace it (if I had to) with a clone for +- $130.00, but I want to return the ati. Could anyone spell out a methodical approach here to get the problem narrowed down. I'd settle for CGA resolution (that's a joke for all you multisync snobs) if I could only see that X could find the mouse, and the board. Believe me, I went through that Xconfig file, and rem'ed out a bit of stuff. I'd email whatever files I can redirect during startx, or X -probeonly, or whatever else I can use. Thanks, Allan =============================================================================== Subject: NEC 3Ds & ATI Vantage I'm STILL trying to get X windows to work in color. I have a ATI Vantage graphics card and an NEC3Ds monitor. After reading all the available info I'm beginning to understand my situation but I wanted to confirm. My card only has 512 M of VGA memory but 1024 if the accelerator chip is used. I believe in VGA mode, the accelerator card is not used, so does this mean I can only use my card at 512M? It seems to me that this is false since I've been able to configure my card in Windows to use SVGA. The ATI people said that the only way the accelerator chips are used is in 8514/a mode. Does this make sense? Now for my X question. I've tried quite a few different setting of the clocks but none have yet to work in color mode. I ran X386 -probe (or whatever that was) and the outsput shows the clocks as 1 2 3 4 ... 16. I expected some more interesting numbers. Am I doing something wrong? I was also curious if anyone has tried the manual clock setting using my configuration. I've ran through the process myself, but a lot of the information I need doesn't seem to be in my manual. Specifically the DCF of my video card. Does anyone have at least this information for this type of card? I'll be faxing a request to ATI soon, but I thought this might be faster. I am using: chipset "ati" videoRAM 1024 and the system does seem to realize that I'm using the 28800 chipset, but it seems to think that my card is a ATI Wonder Plus.

Does this make sense? All true I'm afraid. Take a look at your card. You only have 512k for VGA. I have an older Graphics Ultra (Mach 8), and I'm in the same boat. Your options are: 1) live with it; 2) buy a new video card; 3) port XFree 2.0, which does support the Mach 8 (and presumably the 1024k it has available to it). >Now for my X question.

However, the timings for "1024x768" do not. Here is the information that you need in your Xconfig for Coherent/X to work with your ATI Graphics Ultra in "1024x768" mode as well. chipset "ati" videoRAM 1024k Modes "1024x768" "800x600" "640x480" Clocks 18 22 25 28 36 44 50 56 30 32 37 39 40 0 75 65 Virtual 1024 768 # ATI Graphics Ultra Plus/Pro/60 Hz/Non-Interlaced #Mode horizontal timings vertical timings "1024x768" 65 1024 1120 1264 1360 768 771 778 825 I prefer non-interlaced at 60 Hz over Interlaced at 87 Hz. I have an NEC monitor and it looks good at 60 Hz. Also, you must set the "VGA Memory Size" of your Graphics Ultra Plus/Pro to "1.0MB". To do this, run the ATI "Install" utility and select the "Set Power-Up Configuration" option; then select the "VGA Memory Size" option and choose "1.0MB". Escape from the menus and save the configuration; then reboot into Coherent. Good luck!
