Same/similar problem (except I get a grey vertical-striped screen). I'm also using a Vaio laptop with 310m gpu and Maverick x64
It seems that the new nvidia drivers are unable to read correctly the "custom" EDID necessary for the Vaio as is also noted here: http://www.nvnews.net/vbulletin/showthread.php?p=2324888 In particular it's said: "The driver changed from using read() to using mmap() on the specified CustomEDID file, and apparently that fails for the special files in /proc, which is arguably a kernel bug." In fact I get this warnings in Xorg.*.log [ 7738.656] (WW) NVIDIA(GPU-0): Unable to use EDID file '/proc/acpi/video/IGPU/LCD0/EDID': [ 7738.656] (WW) NVIDIA(GPU-0): unable to map file [ 7738.656] (WW) NVIDIA(GPU-0): Unable to read EDID for display device DFP-0 .... [ 7739.742] (WW) NVIDIA(0): Unable to get display device DFP-0's EDID; cannot compute DPI [ 7739.742] (WW) NVIDIA(0): from DFP-0's EDID. And if I disable the custom EDID option in xorg.conf the warnings are the same except for the first two lines missing and the screen goes the same. -- Nvidia driver version 260.19.06 causing problems on Maverick https://bugs.launchpad.net/bugs/655927 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
