I have obtained flat panel monitor Benq fp71G+. My laptop: Acer tm4222 with intel945G integrated graphics, ubuntu 6.10 operating system. I was trying to get dual monitor config working, but I have failed. Start of the x server fails with a black screen and no error messages. I have managed to get the external screen working in single screen mode. I have tried several configurations options of the i810 driver (MonitorLayout, DevicePresence) and screen resolutions (Mode in Screen section), but non of them worked.
Created attachment 9146 [details] xorg.conf with dual monitor config
Created attachment 9147 [details] Xorg log
At this point, the multihead support in the current release candidate is entirely different, and we can't really support issues found with older releases. Please re-test with current code.
The same does with 7.2 (on Ubuntu 7.04)
Created attachment 9664 [details] Xorg.0.log from xorg 7.2
when I changed driver to xserver-xorg-video-intel (on Ubuntu Feisty and xorg 7.2), clone mode now works. But Xinerama option causes xserver crash. Xorg.0.log and xorg.conf are attached.

Created attachment 9906 [details] Xinerama crash but different errors I get this bug too but with a different log output. See attached around line 475 : (II) intel(0): I2C bus "DVOI2C_E" initialized. (EE) intel(0): detecting sil164 (EE) intel(0): Unable to read from DVOI2C_E Slave 112. And later on line 1059 : (EE) intel(0): I830 Vblank Pipe Setup Failed 0 I still have two or three different xinerama configurations available (I symlink xorg.conf using a homemade script) that used to work on xorg-server 1.1 (around last summer). None of them work anymore with xorg-server 1.3.0.0 and xf86-video-intel 2.0.0
Failure with xinerama is the expected results with the current code, and we have no plans to fix it. You can use RandR 1.2-based configuration, statically (xorg.conf(5) has information in git) or at runtime using xrandr(1), which allows for many common multihead configurations.

...no plans to fix it? Are you kidding? I'd expect a sane error message rather than a traceback...
I have to agree. It's not very nice having X crash just cos you put a special sequence of characters into a file. If the conf parser can't handle it without segfaulting then it doesn't smack of well written and considered code (regardless of how well randr 1.2 and the rest of the actual server stc. works)
You should probably read "no plans to fix it" as "patch welcome" :)
xrandr is preferred method by now.
Will there be a way to work around the framebuffer limitation (which forces me to logically align my screens vertically when they are physically aligned horizontally) ? Will there be a way to work around the memory limitations so that I can use the DRI if I put the Virtual 2048 2048 to "fix" the first issue ?
(In reply to comment #16) > xrandr is preferred method by now. We all know what the preferred method is. I think the main issue was that incorrect syntax in xorg.conf actually CRASHES the server!!! This is not good in any application! As of the 2048 DRI limit, this is technically fixable but involves some hard sums that no-one has stepped up to the plate to implement. Keith P has described what needs done on Xorg mailing list in the past. You can adjust the position of your monitors but it may be that the placement you refer to is to keep them with in the 2048 bounding box?

Please, can we get at least some sort of Xinerama support back? I don't care for fancy features like XV or DRI support. I just want a working dualhead setup for productivity. Currently, RandR is only supported by ATI and Intel AFAIK. All the other drivers require Xinerama for a multihead setup. With the current RandR 1.2 vs. Xinerama conflict, there is a _very_ small subset of possible configurations that can use a multihead setup at all if one of the card is an Intel card. And as Intel is builtin, there is no chance to replace it with another card.
For the records: I worked around this issue by fetching the source of the last pre-2.0 version (1.7.4), fixed it to build against the Xorg 7.3 headers, added the PCI ID of my i965GM and got working dual head using Xinerama. However, I'm afraid of changes in later Xorg versions that don't allow me to compile the old i810 driver anymore. This "solution" is also limited to hardware that is old enough to be supported by the old i810 driver.
