If I set this option to Disable, and if I use PS/2 keyboard and mouse, the computer will enter ACPI S3 state, and resume from it correctly. If I use USB keyboard and mouse instead of PS/2 keyboard and mouse, the computer will enter ACPI S3 state briefly, and comes out of it instantly. For more information about ASUS P5N-E SLI mainboard, refer to this link. http://www.asus.com/Motherboards/Intel_Socket_775/P5NE_SLI I noticed similar problems with ASUS A8N-LA mainboard that came with an HP desktop PC if I performed the same operation with Ubuntu 10.04.4 LTS 32-bit and 12.04 LTS 32-bit. This mainboard also had NVIDIA nForce 430i on it. For more information about ASUS A8N-LA mainboard, refer to this link. http:// h10025. www1.hp. com/ewfrf/ wc/document? lc=en&cc= us&docname= c00647121& dlc=en System Configuration: - Ubuntu 12.04 LTS 32-bit * All updates as of 8/7/2012 have been applied - Intel Pentium 4 521 2.8 GHz * 800 MHz FSB * 1 MB L2 cache - ASUS P5N-E SLI mainboard * BIOS Revision 1406 (last release) 11/18/2009 * NVIDIA nForce 650i SLI (NB) and nForce 430i (SB) - 1 GB DDR2 800 DDR2 SDRAM * Corsair CM2X1024-6400C5DHX 1 GB module * Operating in single channel mode - ZOTAC GeForce 8400 GS * 256 MB DDR3 SDRAM * PCI Express x16 * Using open source NVIDIA display device driver - NETGEAR WG311T Wireless LAN - 32-bit PCI card - Maxtor STM380211 80 GB PATA hard drive - Hitachi LG Data Storage GDR-8163B PATA DVD-ROM drive - USB keyboard - USB mouse - Dell 19 inch LCD monitor * VGA input I believe this is a bug of NVIDIA USB device driver, although I own other NVIDIA chipset-based mainboards, they don't exhibit the same problem (i.e., ECS NFORCE4-A939 and MSI NF980-G65). >From what I have seen, this issue seems specific to NVIDIA nForce 430i. Please fix this bug. I will do anything to help the developers fix the bug. Please note that I don't have physical access to this computer setup at this point because it is currently located in another U.S. state where I visit only twice a year.
