Does the output look reasonable (except that you cannot change the resolution)? If it displays weird numbers, it didn't detect or locate the mode list in your video BIOS correctly. That's what happened for me with the odler version ("855resolution"). The above-mentioned, newer one worked for me. If it displays reasonable numbers for you (i.e. those standard resolutins like 1024x768 etc.), it located the mode list correctly. But if you still cannot change the modes, maybe the video BIOS hasn't been shadowed to RAM (i.e. it's running from ROM, so it cannot be modified). You might check your BIOS setup and look for an option to enable video BIOS shadowing. Or maybe you don't have sufficient permission to write to that area. Maybe tracing the process (strace, truss) might reveal something. > Grr. > Who programmed the 915resolution-utility actually? > It's not really clear from the sources. The first code (for i855 only) was written by Alain Poirier. Several other people (including Damien Bergamini and Steve Tomljenovic) picked it up, improved on it and added support for more intel chipsets. Alan Hourihane integrated the support directly into Xorg's i810 driver, which should show up in the next release (dunno if it's in CVS yet). I have a collection of links on this issue: http://perso.wanadoo.fr/apoirier/ http://damien.bergamini.free.fr/i855vidctl/ http://www.geocities.com/stomljen/ http://www.fairlite.demon.co.uk/intel.html http://people.tecnik93.com/~acpi_perf/ https://bugs.freedesktop.org/show_bug.cgi?id=643 The last link (freedesktop.org) is a fairly interesting discussion of the whole story.
