Re: Re: Boot fails after stretch upgrade to linux 4.9.0
As an alternative solution to disabling nvidia optimus from BIOS, another off-list exchange suggested to force disabling nouveau runtime power-managment. Create a file /etc/modprobe.d/nouveau.conf and add the following to it: options nouveau runpm=0 Then reboot. Works for me (kernel: linux 4.9.0-3-amd64). Thanks, Francesco

Thanks to an off-list exchange I managed to boot 4.9.0 in normal mode by deactivating the discrete graphic card (Nvidia Optimus) from BIOS. The integrated card is good enough for me anyway.

Adding condition on package version pinning (example case: linphone)
Hi, I am on Stretch and the default linphone version is unusable for me (I got reported bugs #743494). However Jessie's version works, so I pinned it in /etc/apt/preferences: Package: linphone* Pin: release n=jessie Pin-Priority: 1001 However, the version is quite old (e.g. lacks of ZRTP support). Is it possible to put a condition such that it should prioritize version 3.6.1-2.4 (jessie) over 3.6.1-2.6 (current on stretch), but upgrade if >= 3.7 becomes available on stretch repositories?

I replaced the thermal paste both on the CPU and the discrete graphic card (just followed the hardware maintenance manual). One thing that I may have not done properly is the quantity of paste, that the manual suggested to be precisely 0.2g. I proceeded with an educated guess rather than measuring it... Anyway, now most of the time the temperature stays below 60C also when video calling (before the maintenance it reached easily 80C with Jitsi), and goes above it (70C-80C) only after few minutes of 100% CPU usage (when before it reached 96C).

Cleaning the fan and especially replacing the thermal grease helped to reduce the max temp from 96C to less than 80C. Enabling the package 'thinkfan' with default configuration also helps reducing further ~5C, and to slow down the rise in temperature when above 60C. Regards, Francesco

Indeed, now it works nicely, temperature max always around 60C also after several minutes of intense CPU usage. Thanks for the help! Francesco

Indeed, this sounds like a great solution for me. Limiting CPUs to 80% does
not increase terribly the execution time, and with thinkfan active it stays
below 70C when running the same code that I was testing before (without
thinkfan it reaches 80C). I attach below the scripts that I am using to set
the cpu limit at boot time by enabling "systemctl enable
set_cpu_max_perf_pct".
Thanks,
Francesco

Re: ThinkPad fan
Hi, Thanks for the suggestions. I tried the following, which didn't change much the situation. Can it be that the CPUs just warm up more when getting old, or it shouldn't matter if cleaned properly? a) I disassembled and cleaned the fan. Fairly dusty (it's about 5 years I have the laptop), I used a vacuum cleaner to remove the dust. I have the impression that the fan now pushes out more air. b) I installed and configured thinkfan (despite the buggy installation [1]). The package description [2] says it is helpful in the case the fan is running too much (not really my problem), but it actually provides an easy way in general to set the fan levels for given temperature ranges [3]. In comparison to before, the fan runs faster now when above 60C. c) I also tried to turn on by hand the disentangled mode (~5500rpm instead of ~4500rpm) [4]. d) I had a look to the script suggested by Tom (thanks), but didn't try it since I managed to install thinkfan. FYI, I think that /proc/acpi/ibm/thermal is no longer the way to get the temperature. For "normal" use (browsing, video, music, ...) the temperature stays below 60C using thinkfan. When I run with CPUs at 100% it reaches 90C in less than two minutes. For work I need to launch short (few minutes) but CPU expensive runs (mostly numerical integrations) on a daily basis. I'll ask around if someone can lend me one of those fan pads to try it out.

ThinkPad fan
Hi, I recently installed Jessie on a Lenovo ThinkPad T420. The fan usage looks reasonable. However, high temperatures (96 C) are reached when CPUs are running intensively for more than one minute or so. The fan speed at those temperatures is about 4500 rpm. Do you think it is ok, or do you suggest to force lower temperatures, e.g., with thinkfan [1]? Thanks, Francesco [1] https://packages.debian.org/jessie/thinkfan
