I have some problems with acpi on my laptops: first laptop is a Compaq Evo N800v: - Lucid Puppy 5.2.8 installed in frugal mode - Xorg_High-1.1-Lucid.pet installed - acpitool-0.5.1-i486.pet installed if I run acpitool -s it suspends correctly, but when I press power on all the laptop awakes except video display. So the screen is black, if I press caps-lock the led works, if I press ctrl-alt-F1 and then ctrl-C I am still able to (blindly) type reboot... It seems that the video adapter is not able to awake. note: on the second laptop, a Compaq 6720s, if works perfectly. Any suggestion? I have also some problems of heating that causes video flickering when temperature raises. When the pc is cold all works fine, as in a few minutes temperature raises the display starts flickering. At the beginnign pressing and releasing the lid button is a momentary workaround to turn the display on. as temperature raise more the computer is pratically unusable. using acpi-cpufreq with ondemand governor give me more time before the problem arise (cpu works most of time at 1.20Ghz instead of 1.80Ghz) using Xvesa instead of radeon video drivers is a good workaround in spite of performance (glxgears runs 500 instead of 5000) using software that do lot of things on screen or use lot of cpu the problem arise earlier. applying a strong pressure with fingers on some points of the laptop is a desperate workaround for a few seconds... amazing but true! note: external monitor seems not suffer of this problem. I am trying to keep the laptop cool raising fan speed but I was not able to modify trip_points (they seems read only on lucid puppy), I tried also the commands: echo -n 0 > /proc/acpi/fan/C1DC/state echo -n 0 > /proc/acpi/fan/C1DB/state echo -n 0 > /proc/acpi/fan/C1DA/state echo -n 0 > /proc/acpi/fan/C1D9/state that activate the fan at max speed but after 4 seconds they turn back to low speed. Any suggestion? second laptop is a Compaq 6720s: - Lucid Puppy 5.2.8 booted from usbkey (windows7 on HD) - acpitool-0.5.1-i486.pet Problems with Lucid CPU Frequency Scaling Tool 0.7 (present in distro): no one of the drivers listed is accepted except of p4-clockmod, this driver is warned not to work correcty in the banner of the Frequency Scaling Tool, and really I was not able to activate ondemand governor. it only works with performance governor with a fixed 1,8Ghz speed heating very much the laptop and putting fan at high-speed all the time, or with powersave governor with a fixed 222Mhz speed, so slow that the system is not usable. the cpu is a Celeron note: on the first laptop, a Compaq Evo N800v, driver acpi-cpufreq works fine with ondemand governor, driver p4-clockmod have same problems. How to activate a working driver with ondemand governor? -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
