 Posted: Fri May 27, 2005 4:35 pm Post subject: dual head woes on the intel 855GM |
 |
|
I'm trying to get dual head working on my laptop (lifebook p7010) with a 855GM intel graphics adapter. I've been working on this constantly for far longer than my eyes can handle, and I've been reading through a lot of posts on the issue. Any help will be much appreciated. This is my xorg.conf for the moment.

It's not dual head, but I've made sure everything's there to make the two screens working. The lines that are commented are the ones I've been playing around with in order to get dual head working. Whatever I do, I normally get either one of these two messages on the external screen: 1) Resolution too high, set to 1280x1024, or 2) Check cable.
cat /var/log/Xorg.0.log | grep WW might give something like this:
| Code: | (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(WW) Open APM failed (/dev/apm_bios) (No such file or directory)
(WW) xf86OpenConsole: Could not save ownership of VT
(WW) I810: More than one matching Device section for instances
(WW) I810(0): Bad V_BIOS checksum
(WW) I810(0): Bad V_BIOS checksum
(WW) I810(0): Primary Pipe is B, switching off second monitor (0x100)

I can't remember, but I tried it on hp nx9020 with i855, but I found somewhere (don't ask when or where, It is forgotten) that dual isn't working with xorg. I think that it might work with xfree.
O.K. It was relatively long ago, so I don't know how it is going now, so do not trust me 100 % !!! This may be compete bullshit nowadays .... |

| Alright. Thanks for the input though... that's too bad if you're right. It's pretty alright as I can manually change and screens, so I can work with a larger screen if I want; but I'd so wanted to have clone or xinerama working... |

It was fixed in xorg's CVS a few days ago although it took a fair bit of time to fine tune the bug fix. You can find the full gory details here...
https://bugs.freedesktop.org/show_bug.cgi?id=1064
You needn't wait until the next xorg version; while fine-tuning the driver he put a steadily updated precompiled version which can be copied directly into an existing xorg 6.8 installation and then dual-head works perfectly! If you're lucky you may still be able to get it here...

Hey, thanks alot! The driver was still there  However, I'm having problems still. Firstly, dri fails due to version mismatch [Edit: I just saw that he mentions it on the download page ]. Secondly, I still can't get dual head working- but this time it might really be my configuration.... |
