Bug#345509: xserver-xorg: 2nd monitor in xinerama setup gets no signal



merge 345509 332548
stop

Hi,

I'm replying to all mails for this bug as I never received any of them
via mail.

Regarding the Warning about MergedFB/Cline mode, I do get the same
warning when using 6.8.2 and in fact I don't want to use MergedFB mode.

Regarding switch to MergedFB: While MergedFB seems to be more stable
now, it doesn't support my setup. I want to have the full resolution on
my primary head (which is 1680x1050, Laptop-Display) and different
resolutions (ranging from 1400x1050 to 1024x768) on the 2nd head. The
used CRT's are changing depending on where I'm sitting at. Now to not
have to reorganize all apps that run in the area the 2nd head displays I
used a virtual resolution of 1400x1050 in Xinerama setup.

When I now say that I want a FB-Area as large as 3080x1050, the CRT gets
a resolution it doesn't support and thus it uses a vertical refresh rate
of 60 Hz which of course is really bad for my eyes. I tried playing
around with the options but it doesn't matter, always have 60Hz on the
CRT.

I also read the other 2 bug reports which seem to address the same
problem, but none of the workarounds mentioned there work here.

However I can confirm that X11 actually is thinking that it has a proper
Xinarama desktop, thus I'm pretty sure the problem is the radeon driver.

Attaching the log from the last try (leaving out the HSync/VRefresh
information from xorg.conf).

Andreas
