This bug was detected using an Acer AL2416W monitor. Details of this device, including timing specifications can be found at http://csd.acer.com.tw/acer/URMUL1.NSF/1af87a750eeeb70f0825628f006e0bfc/090e4352ee164afe4825709200141575/$FILE/AL2416W%20p%20user%20manual%20.pdf The highest resolution supported by this monitor is 1920x1200 (@60). This monitor is successfully driven at this resolution by Win98SE with nVidia binary drivers through a GF4800. Extracting the effective modeline from Win98SE using arcane magic suggests 153.56 1920 1984 2016 2080 1200 1203 1209 1235 +hsync -vsync which is readily apparently unlike the modeline suggested by the above-linked manual, but may be informative. Software version numbers and a hardware description are given below. When using the "nv" generic driver, the 1920x1200 and 1600x1200 modes do not work. None of the modelines extracted from the Win98SE machine, those automatically generated (as listed in a giant block in the Xorg.log file), those suggested by the above manual, nor those copied exactly from the "nvidia"-using xorg.conf work. When using the "nvidia" binary driver, version 1.0.8756, the 1920x1200 and 1600x1200 modes work. The explicitly listed modeline above is used by the nvidia driver. Expected behaviour: Generally, that automatically detected display video modes will be successfully driven by the "nv" driver module. Specifically, modelines identically copied from a working "nvidia" xorg.conf file will produce working video modes under the "nv" driver. Observed behaviour: the "nv" driver cannot be coerced to drive the Acer AL2416W monitor at its highest (vertical) resolution, using modelines from any source. Hardware details: AL2416W monitor video is nVidia C51 (GF6100 integrated into nForce 430 chipset), 128MB shared Athlon X2 4800+ 4 GB, PC3200 SDRAM Software details: Kubuntu "Dapper Drake" 6.06 beta2 for AMD64 (daily updated from 25 April to 02 May 2006). This bug was replicated on each of the daily updates. Linux 2.6.14 and 2.6.15 xserver 7.0.0 (several packaging releases, but no content updates) nv driver 1.0.1 (compiled for 7.0.0, ABI class X.Org Video Driver, version 0.8) nvidia driver 1.0.8756 (compiled for 4.0.2)
Created attachment 5551 [details] xorg.conf and Xorg.0.log files for nv and nvidia configs The configuration files and startup log files for the "nv" and "nvidia" driven setups are attached. Extract as tar -xvzf xorg_files.tar.gz producing the folder xorg_files containing four files. The "nv" files are suffixed with ".nv" and the "nvidia" files are suffixed with ".nvidia".
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
xf86-video-nv has been officially unmaintained for a bit now, and we are closing all -nv bugs. If your problem was not addressed, and -nv is still broken, please try xf86-video-nouveau. Thank you.
