It works for me on the 500m as well, with v0.2 of 855resolution.

Run "855resolution 3c 1400 1050" at boot, and XFree86 will allow that resolution. I run Debian testing with XFree86 v4.3.0.1. I also run 855patch make more video memory show up, I don't know if that is needed anymore (at least, it shouldn't be in XFree86 v4.4 & X.org).

Great work by Mr.Poirier for doing what Dell should have done a long time ago.

what is the output of the 855resolution when you run it on your 500m? What VBIOS version and type do you have? I've tried running it on my laptop, but have errors and not success :-(

cheers

855resolution v. 0.2 works perfectly on my 500m 1400x1050 with BIOS A06 or A07 (not sure).

I do a "855resolution 3a 1400 1050", select 1400x1050 with Mandrake 10's display configuration, and everything works as a charm. Version 0.1 didn't work, its -l option only showed resolutions which didn't make sense.

Big thanks to Messrs. Zietz & Poirier for their 855patch and 855resolution utilities which make this laptop usable with Linux and XFree86/Xorg! Do they accept donations, e.g. PayPal?

And shame on Dell for still not fixing the BIOS!

Once I generated a modeline using the online calculator, it works like a charm. Very happy :-)

I don't use any modelines, it works like a charm as well.

I've only tinkered once with external output. I think I've got it working on an external LCD before, but never with a CRT. I'll be looking into this in the next few days and I'll let you know what I find...

Cool, thanks! I'll just stress that I have no problems getting an external monitor (CRT) to work. The problem is to get an internal and external monitor to work at the same time (e.g. in Xinerama mode).

Chipset: 855GM
VBIOS type: 1
VBIOS Version: 29

The output from 855resolution looks otherwise normal, with predictable resolutions. Have you tried v0.3 that came today? It might work better for you.

One other thing: Has anyone managed to get the internal and external display to work simultaniously? I can only get them to work one at a time under Linux. With Windows, I get them working at the same time without any problems.

thanks, this is the same as mine. My problem was that the programme generates invalid modelines. I had a look through the source last night and found this comment:

/* WARNING: I don't know at all what are the formulas to calculate these values ! The following lines are only an example.*/

yep, that was why I was initially confused. Why did my Xserver require a modeline and everyone else's just work? The script can't have been generating valid ones, so there must be something different happening in the different distros...

I too have managed to get the external working alone, but I need to test it in mirror mode (i.e. see the same thing on the internal LCD as well as the external monitor). I need my laptop to do presentations. I've also not had success getting things working with the "extended" mode where the external screen becomes a second monitor.

cheers

I forgot the dri.log message:
"rm -f *.o *.ko dristat drmstat .depend .*.flags .*.d .*.cmd
make: *** No rule to make target `gdg.ko'. Stop."

It seems like Intel has released new drivers (IntelGraphics_060704.tar.gz) for this graphics chipset, with support for dual head operation:

http://downloadfinder.intel.com/scripts-df/filter_results.asp?strOSs=39&strTypes=DRV%2CARC&ProductID=922&OSFullName=Linux*&submit=Go%21

I can't get them to compile, though. I am running debian testing with a 2.6.7 kernel. Here's the error message:

"Compiling new agpgart module...
Compiling DRM module...

ERROR: Kernel modules did not compile

The DRI drivers can not be installed without the latest kernel modules.
Installation will be aborted. See the dri.log file for information on
what went wrong."

Oh well...
