I have a Permedia2 in my test machine and the tool behaves properly. The config tool tries to determine the available resolutions based on the amount of probed video card memory and the monitor refresh rates. Sometimes if the monitor cannot be probed properly, the tool will default to a Generic monitor with a low refresh rate which causes the list of availabe resolutions to be limited. In this case, it is necessary to manuall select the correct monitor in order to see more resolutions. Try this: 1) delete /etc/X11/XF86Config (or move out of the way) 2) run 'redhat-config-xfree86' 3) See if you can select "1024x768". If not, go to step 4 4) click on the "Hardware" tab and see if the correct monitor was probed. If not, select the right monitor. 5) Go back to the "Settings" tab and see if you can select "1024x768" now.
Ok, think there is still sth. wrong: here's the steps I did 1) delete /etc/X11/XF86Config (or move out of the way) ok 2) run 'redhat-config-xfree86' first ddcprobe: bogus results tries to start i845: fails second ddcprobe: bogus results starts with permedia2 3) See if you can select "1024x768". If not, go to step 4 no i cannot select 1024*768 4) click on the "Hardware" tab and see if the correct monitor was probed. If not, select the right monitor. I must select a similar monitor: adi microscan 5v+ mine is Sun CHB7727L 5) Go back to the "Settings" tab and see if you can select "1024x768" now. yes now I can select millions of colors (probably wrong? card cannot do this?) select OK after that I startx, get 800*600 85hz ! (first problem?) quit X, start redhat-config-xfree now I select 1024*768, thousands of colors, OK, startx I get again 800*600 85hz (second problem?) quit X, delete XF86config. start redhat-config-xfree select monitor, 1024*768, thousands of colors(difference!), OK, startx Now it's ok 1024*768 Hope it's not to confusing, what I have written! :)
Ah, ok. I think I might see the problem. I think that the ADI MicroScan 5V+ monitor that you are manually selecting is quite different from your actual Sun monitor. From documentation I've found on the web, it looks like your Sun monitor is made by Samsung and has different refresh rates than the ADI. For example, according to our monitor database, the ADI 5V+ has a horizontal refresh rate of (30.0-64.0) kHz and a vertical refresh of (50.0-100.0) Hz. According to http://sunsolve.sun.com/handbook_pub/Devices/Monitor/MONITOR_Color_17_Entry_CRT.html#365-1396 the Sun monitor has refresh rates of (30.0-72.0) kHz and (50.0-160.0) Hz. As you can see, the Sun monitor is capable of higher refresh rates than you were setting it to. The closest thing in our monitor list is the "Samsung SyncMaster 710(M)b (CHB7709*)". Try selecting that monitor and see if the problem doesn't go away. You should be able to use 1024x768 no problem with that monitor. Just for completeness, I've added an entry to our monitor database for this monitor as "Sun 17-inch CHB7727L (Samsung)" with the correct refresh rates, which should appear in hwdata-0.100-1.
