Interesting point WRT being driven out of spec. I've not investigated properly yet, though. WRT runlevel 3 - that is *very* useful. And what's more, while Googling how to do that, I also found out about ctrl-alt-F1 etc, which is also cool. I particularly like the idea of being able to run in a VM without the X overheads, though, by booting in runlevel 3. I knew this was possible, but haven't looked into how since the days of Mandrake 8. I'm curious why it's ctrl-alt-F7 to get back to X, and ctrl-alt-F8 just gives me a black screen. Presumably, the 7th terminal is just where X gets started by default? Anyway, I can't seem to recreate the issue just at the moment, either booting as normal or going in via runlevel 3 then startx. Standard for intermittent faults, I guess - they run and hide when you're trying to find them. >> Boot in failsafe and (with the lower resolution) everythings fine.

It seems to think I have three monitors, each identical barring a different unique ID. There's only one. My card has three outputs (DVI, VGA, TV), but I'd be surprised if this triple listing has anything to do with that. BTW - I did notice this in YaST, but I got distracted and forgot about it. 2. "Each" monitor has two "detailed timings" sections with slightly different timings - e.g. one has 60.00 Hz, the other 59.93 Hz. I'm still very much leaning towards the "graphics card driver is confused" theory. Anyway - the "hwinfo --monitor" results... 30: None 00.0: 10002 LCD Monitor [Created at monitor.95] Unique ID: rdCR.Uw6VfaNSQS8 Hardware Class: monitor Model: "LG ELECTRONICS W2261" Vendor: GSM "LG ELECTRONICS" Device: eisa 0x56ce "W2261" Resolution: 720x400(a)70Hz Resolution: 640x480(a)60Hz Resolution: 640x480(a)75Hz Resolution: 800x600(a)56Hz Resolution: 800x600(a)60Hz Resolution: 800x600(a)75Hz Resolution: 832x624(a)75Hz Resolution: 1024x768(a)60Hz Resolution: 1024x768(a)75Hz Resolution: 1280x1024(a)75Hz Resolution: 1280x1024(a)60Hz Resolution: 1280x960(a)60Hz Resolution: 1152x864(a)75Hz Resolution: 1920x1080(a)60Hz Size: 477x268 mm Detailed Timings #0: Resolution: 1920x1080 Horizontal: 1920 2008 2052 2200 (+88 +132 +280) +hsync Vertical: 1080 1084 1089 1125 (+4 +9 +45) +vsync Frequencies: 148.50 MHz, 67.50 kHz, 60.00 Hz Detailed Timings #1: Resolution: 1920x1080 Horizontal: 1920 1968 2000 2080 (+48 +80 +160) -hsync Vertical: 1080 1083 1088 1111 (+3 +8 +31) +vsync Frequencies: 138.50 MHz, 66.59 kHz, 59.93 Hz Driver Info #0: Max.

The ATI drivers that I've used were junk. However, your vertical resolution is an HDTV[1] standard, so I'd be surprised if the ATI drivers couldn't handle it. [1] Yes, if I were buying a TV then I'd want 1080p. But on a computer monitor I'd rather have 1200 or more, TYVM. -- Shmuel (Seymour J.)
