Bug Description
Currently ubuntu hoary selects wrong default resolution for most monitors I
tested :(
on most my tested systems (17' CRT monitors) ubuntu hoary live starts in
1280x1024 resolutions, which is really not good for these monitors, most people
use 1024x768 or 1152x864
fonts are very small when using 17' CRT monitor with 1280x1024 resolution and
refresh rate is 60 or 75 Hz, which is really bad, according to TCO99 standard
vertical refresh frequency *must* be >=85Hz (look at Section 2 (Visual ergonomic
- Image stability) of TCO99:
http://
There is simple table of mandatory resolutions and vertical refresh for CRT
monitors:
CRT Size VRefresh Resolution
14"-15" >=85 Hz >=800x600
17" >=85 Hz >=1024x768
19"-21" >=85 Hz >=1280x1024
>21" >=85 Hz >=1280x1024
Btw, TCO99 recommended vertical refresh is 100Hz and I think it would be very
nice to select according display mode if possible (if monitor could work with
mandatory resolution at 100Hz)

Er, most monitors won't do 85Hz or 100Hz in any real mode; only higher-end ones.
I think a better metric to aim for is above 70Hz; the mode selector should be a
little more intelligent here, but at the moment, it's a shell hack.
