[Dapper Flight 6] Too high a resolution is used, by default, on a 15 inch CRT monitor

[John Doe]

I have a computer with an AGP S3 Savage 4 (I think it is branded "Diamond SpeedStar A90") video card and it has a 15 inch NEC Multisync C500 CRT monitor. When I boot the Ubuntu Dapper Flight 6 live CD, the resolution chosen (1280x1024 @ 60hz) is a bit too high and makes the text very hard to read unless you have good eyes. 800x600 on this monitor is MUCH more readable.

This is the output of "lspci -n"

This is the output of "discover --disable=parallel,serial,usb,ide,scsi,pcmcia --format="%S\t%D\n" video"

This is the output of "xresprobe savage"

Hi,

Thanks for reporting this. It seems X is using the correct resolution with respect to your hardware. You can reduce the resolution in gnome from the System -> Preferences -> Screen Resolution settings. Also note that the 6.06 live CDs will have several accessibility features from the boot screen (press F5) one of which is a high contrast setting with large fonts and another uses a screen magnifier.

If you still feel this issue needs better provision I would encourage you to look at the feature specification procedure: https://wiki.ubuntu.com/FeatureSpecifications.

What I don't understand with this is why Ubuntu's Xorg goes and picks the only resolution that can't have a refresh rate higher than 60hz on a CRT monitor. Wouldn't it make more sense to lessen potential eye strain (and I am particularly irritated by the 60hz flicker and know of others who notice it by the headaches they get by staring at a 60hz computer screen) by having only the highest resolution that can do something higher than 60hz be picked on this monitor?

In Dapper 6.06 Beta, this still is an issue. Upon boot of the 6.06 beta live CD, X.org still picks 1280x1024 @ 60hz on a 15 inch CRT monitor. This monitor can do 75hz @ 1024x768 and 75hz at 800x600 yet the resolution chosen at boot by the Live CD (of 6.06 beta) and an installation (of Dapper Flight 6, I believe) is 1280x1024 @ 60hz, which is the only resolution that can't do 75hz, meaning the screen is nothing but a huge irritation for anyone using that machine unless they hand-edit xorg.conf. If I comment out the refresh rates chosen and get rid of the "1280x1024" out of all the Mode lines, 75hz is chosen automatically by X at 1024x768.

It would be great if 1024x768 @ 75hz was chosen instead of 1280x1024 @ 60hz when the Live CD loads or when doing a fresh installation.
