To this I provided my first reponse 30 minutes later asking for more information, which you provided about 18 hours later, Tue, 1 Jan 2008 12:33:20 -0500. In reply 1 hour and 24 minutes later, Jan Ritzerfeld pointed you to the relnote page telling you to do 'sax2 -r -m 0=i810'. In reply to Jan 1 hour 16 minutes later you questioned the logic of the instruction and digressed into what might happen if it didn't work. 27 minutes later Jan responded again, including a reiteration of the propriety of 'sax2 -r -m 0=i810'. Meanwhile, roughly 2.5 hours after your Tue, 1 Jan 2008 12:33:20 -0500 post, I made my reply to it, pointing you to the same relnote link containing 'sax2 -r -m 0=i810' as Jan. Since that post up until your report 3 days 2 hours and 48 minutes later that 'sax2 -r -m 0=i810' worked there were another 16 posts in the thread, both on point and digressions, including Wed, 2 Jan 2008 18:31:18 -0500 your report of the negative consequences of running 'sax2 -r -m 0=i810' without first closing X. > (thanks, Felix for the instructions).

On Thu January 3 2008, Felix Miata scratched these words onto a coconut shell, hoping for an answer: > On 2008/01/03 18:51 (GMT-0500) Gil Weber.com apparently typed: > > So is there something fundamentally wrong between Sax2 and my > > motherboard that is going to prevent me from getting this video > > problem fixed? > > Possibly. > > > Am I just spinning my wheels > > Probably not. > > > and wasting your guys' time? > > Wasting is probably not quite accurate. Sorry, poor choice of words.

Yes, it can!! Felix, Jan, Rajko, Ken, Aaron: Many thanks to all of you for your expertise and patience. Using your helpful suggestions I have been able to fix the problem -- at least it is significantly better than before. :o) I finally was able to run 'sax2 -r -m 0=i810' from a command line (thanks, Felix for the instructions). After logging back into the GUI my rectangles are nearly perfect! The fractional amount of horizontal vs vertical difference is so slight it is easily ignored. As comparison, prior to switching to the i810 driver I had: 1152X864 (XGA), 72X64 DPI, and 1152X768 pixels (significantly sub-optimal) After changing drivers I am able to get: 1280X960 (QVGA), 80X79 DPI, and 1280X960 pixels (not state-of-the-art, but a major improvement). Measuring the 1" horizontal bar on one of Felix's test screens my monitor now shows that 1" bar as 1 1/32" (as I said, a difference easily ignored). And on another of Felix's test screens the horizontal and vertical dimensions of squares are only slightly off. So I am thrilled to have rectangles displayed as rectangles rather than as squares. FYI, here are the outputs of some reports from the console after the driver switch: [EMAIL PROTECTED]:~> xdpyinfo | grep resolution resolution:80x79 dots per inch [EMAIL PROTECTED]:~> xdpyinfo | grep dimensions dimensions:1280x960 pixels (406x309 millimeters) Yahoo!! :o) Also from the xorg.conf file (edited here to conserve electrons) confirming the i810 driver rather than the intel: # /.../ # SaX generated X11 config file # Created on: 2008-01-04T10:50:12-0500.

Previously I had described that the countdown timer in the upper left hand corner of sax2 did not countdown, and the buttons for changing screen dimensions did not work. After changing to the i810 driver using the command line those conditions remained unchanged. No countdown and no changes possible with the on-screen buttons. As previously, I had to change screen dimensions with the controls on the front of the Viewsonic monitor. So the i810 driver fixes some but not all of the issues with the upgrade to 10.3.

This was a huge learning process for me. Hard to put so much into my head in such a short time. :o) (snip) But I do have one more related issue to toss out to all of you. Many of your communications described DPIs well above 90. Jan even noted that he was getting 129X126. Incredible. Felix suggested that to get to around 96DPI I would need to up my resolution to 1400X1050. Remember that I don't have a nice, modern video card. I am using the onboard chip. Is there potential for damaging the chip or some other component in my system by pushing the video driver that hard? For example, if one were to seriously overdrive a microphone preamplifier you could do some real damage to the electronics. Or if you seriously overdrive the preamplifier in a stereo system you can damage other (downstream) components as a result. Could a similar thing happen here by raising the resolution so high? Or is it simply a matter o
