Package: wnpp Severity: wishlist * Package name : vbetool Version : 0.1 Upstream Author : Matthew Garrett <[EMAIL PROTECTED]> * URL : http://www.srcf.ucam.org/~mjg59/laptops/ * License : GPL Description : run real-mode video BIOS code to alter hardware state
vbetool uses lrmi in order to run code from the video BIOS. Currently, it is able to alter DPMS states, save/restore video card state and attempt to initialize the video card from scratch. vbetool is primarily useful for attempting to recover from ACPI S3, since most hardware leaves the video card in an undefined state. Since it uses vm86, it will currently only work on x86 hardware - in the long run, I'd hope to move it over to Scitech's x86emu and give it more portability. It's also currently in the form of three separate tools, but I'll merge those in the near future. Currently, the combination of: switch away from X vbetool savestate >foo vbetool dpms off (suspend) vbetool post vbetool restorestate <foo vbetool dpms on switch back to X seems to work on a fairly wide range of hardware. Of course, this all interacts badly with framebuffers - there's an argument for getting the kernel to try to get userspace to do this before it attempts to resume framebuffer devices. But we'll cross that bridge when we come to it. -- System Information: Debian Release: 3.1 APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.9-1-386 Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8)
