Attachments:	Script to ensure a sane monitor resolution on old monitors xorg.conf for monitors that do not return edid info

Description Dave Hodgins 2012-10-12 03:25:58 CEST

When booting any of the live iso images on a system using
the fglrx driver, and a monitor that does not support edid,
the default resolution is 1600x1200, which is too large
for older monitors.

Using alt+ctrl+f2, logging in as root, running XFdrake,
and changing the resolution from automatic to 1280x1024,
and then running "service dm restart", allows me to use
the live cd/dvd for both kde and gnome 3.

Script to ensure a sane monitor resolution on old monitors

Instead of patches, I have two files to add to the draklive-install package.

This one should be added as /etc/X11/xinit.d/checkoldmonitor

As expected, this bug is back with the current final live iso images.

If defaulting to a resolution of 1024x768, when the monitor does not
return edid information, is too annoying, perhaps forcing the driver to vesa could be used.

I think this bug should be considered a release blocker, as it
will make the live isos useless for most people who have old
monitors and new video cards.

When booting from the kde x86_64 dvd in uefi mode, the safe mode
option works.  Perhaps that could be added as a boot option for
all live isos.

Comment 7 Thomas Backlund 2013-05-12 20:38:55 CEST

its not only old monitors, it's also new hw with crap edid data

a ~month ago I saw a laptop that reported full hd according to edid, but in reality the laptop had a ordinary screen :)

but at this point the "Safe Mode" boot option would probably be good to add
to standard live mode boot... otoh you can use F6 to change options yourself,
but maybe it's a more newbie-friendly option to have a simple entry to choose.

I added "Safe Mode" for UEFI boot as you cant change boot options from the menu for now...
