Not yet, but I don't know what else could have caused this. I have used scan (same thing as just pressing enter) and I get about 50 valid modes to enter. Everything thing from vga to 1920x1200. I have tried entering the listed modes (e.g. 31A) and it just gives me the same 'invalid mode' prompt. I've been through the KMS page that just refers you to https://wiki.archlinux.org/index.php/NVIDIA for nvidia cards. This card is an 8800GT so I have always used: # pacman -S nvidia nvidia-utils to install the driver and I've never had any issues. I haven't specifically set anything for KMS with nvidia boxes. So I'm at a loss at what changed. The problem I have is that I don't know what process does the mode check and then throws the invalid mode error? Is it a kernel process, nvidia driver process. (I suspect a driver process since it is setting the framebuffer, but I could be totally wrong) I'm open to all suggestions. I'll give the downgrade a try tomorrow or Friday when I get a chance. Thanks for the suggestions. -- David C. Rankin, J.D.,P.E. Rankin Law Firm, PLLC 510 Ochiltree Street Nacogdoches, Texas 75961 Telephone: (936) 715-9333 Facsimile: (936) 715-9339 www.rankinlawfirm.com
