For me it is a downhill....For me it is a downhill....Posted Jul 20, 2005 13:09 UTC (Wed) by nhasan (guest, #1699)Parent article: Kernel Summit 2005: The power management summit
I have a Dell I8K and I have been using SUSE on it since I bought it. My experience with power management on this laptop is going from bad to worse in the suspend area. At first I was able to Suspend-to-RAM and restore successfully even while running X. After upgrading to SUSE 9.1, I could not longer succefully restore the system if I suspended while in X. I had to exit to console to suspend. Recently, I upgraded to SUSE 9.3 and now that does not work either and I am forced to shutdown every time. What a waste of time.

For me it is a downhill.... Posted Jul 31, 2005 9:04 UTC (Sun) by marineam (subscriber, #28387) [Link] I also have a Dell I8K, and have managed the reverse. Although I run Gentoo, not SuSE. Using Suspend2's hibernate script which will unload modules for troublesome hardware clears up most problems. Both suspend to ram and disk work using that script. The only tricky part is doing suspend to ram with the framebuffer enabled. With no framebuffer Gentoo's Xorg can take care of reinitilizing the video card (ATI), but to suspend with the console frame buffer enabled a kernel patch is required. I have no idea what the status of the Nvidia video cards is though.
For me it is a downhill.... Posted Aug 8, 2005 21:18 UTC (Mon) by barrygould (guest, #4774) [Link] I have a Dell D800, which I believe is about the same as the I8000.
On it, enabling the power-on password in the BIOS solves the video-reset problem when using the NV driver.
However, it does not work if using NVidia's driver.

For me it is a downhill.... Posted Aug 16, 2005 18:15 UTC (Tue) by EricBackus (guest, #2816) [Link] I have a Dell I5000e, which I believe is one generation older than theI8000. I've had mixed results with power management, but I can't really say it's been downhill, more sideways. Originally, I used APM, which allowed me to suspend-to-RAM successfully and also allowed some kind of "standby" mode. The kernel didn't support suspend-to-disk, but the BIOS actually has a built-in suspend-to-disk that can be used (but don't use it, it's very slow and somewhat buggy). Over time, the ACPI code in the kernel got to where it works fairly well with this laptop, and today that's what I use. I can suspend-to-disk with this. However, suspend-to-RAM doesn't work at all, nor does standby, and ACPI goes crazy (dumping messages to /var/log/messages fast enough to fill the disk quickly) if I close the laptop lid when the laptop is powered up. I'm running SuSE 9.3 now, so I can verify that suspend-to-disk works on the I5000e. In spite of Linus's comment, I'd have to say that suspend-to-disk is the most important power management mode, so I'm actually reasonably happy today.
