| gnarface | nomia: make sure you specify the repo hostname on the debootstrap command-line or it's gonna be trying to debootstrap your devuan from armbian sources | 01:48 |

| FatPhil | one of our laptops is running horribly hot - it's mostly idling, but it's over 70C (I'm under 50C on my similar laptop under higher load) | 14:59 |
| FatPhil | the fan doesn't seem to have spun up, can I persuade it to shed some heat somehow? | 15:00 |
| gnarface | uh... some sort of control over thermal thresholds may be possible in /sys if drivers support it maybe? | 15:06 |
| FatPhil | fan2_input under sys/..../hwmon/ reads 65535, which doesn't sound like a real RPM value, it sounds like an error | 15:32 |
| gnarface | hmm, yea... support for this stuff tends to suck in general | 15:34 |
| gnarface | what do you have the cpu governor at? | 15:35 |
| gnarface | cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor | 15:35 |
| gnarface | is it the same on both laptops? | 15:35 |
| gnarface | that could cause a big difference in idle temps | 15:35 |
| gnarface | and do you have lm-sensors installed and configured? i've seen laptop fan rigs that need to be goosed by the temperature sensors driver just to work | 15:36 |
| FatPhil | they weren't installed - just installing fancontrol, lm-sensors, and thinkfan... | 15:38 |
| gnarface | sheesh, make sure you have acpi installed | 15:39 |
| gnarface | you might just want to go ahead and install task-laptop but maybe that's overkill, not sure | 15:39 |
| FatPhil | all 4 cpus are saying powersave on both laptops | 15:39 |
| gnarface | fancontrol probably is useless except on super old hardware now, and even for that stuff its own docs advise you not to use it... | 15:40 |
| gnarface | after installing lm-sensors though you'll want to run sensors-detect as root and answer yes to all questions | 15:40 |
| gnarface | thinkfan i'm not familiar with | 15:41 |
| gnarface | but the other thing to check is the actual system bioses... sometimes there will be fan aggressiveness presets | 15:41 |
| gnarface | it may have like a performance mode and a quiet mode and a medium mode | 15:42 |
| FatPhil | I notice that I don't have any of those three packages on my (behaving) thinkpad. | 15:42 |
| gnarface | hmm | 15:43 |
| gnarface | yea, check the bioses | 15:43 |
| FatPhil | I did have to use fancontrol on my MSI Cubi box, but that was to get it to lower the fan aggressiveness. | 15:43 |
| gnarface | maybe it's just a model difference or a hardware load difference? heat can come from gpu or wireless devices instead of cpu load for example? | 15:44 |
| gnarface | just guesses | 15:44 |
| FatPhil | yeah, these are different model thinkpads, alas | 15:44 |
| FatPhil | hers didn't always use to be this way, she only noticed it today, she's had it years | 15:45 |
| FatPhil | powertop did say that GPU was at 100% | 15:46 |
| gnarface | that seems conspicuous | 15:46 |
| gnarface | for an old laptop you might want to make sure the fans are even working too though | 15:46 |
| gnarface | not sure how exactly | 15:46 |
| gnarface | but if you're desperate to cool it down and not afraid to disassemble it, re-applying some higher quality thermal compound than they use at the factory stock can help a lot, if you do it just right (a common mistake is to use too much) | 15:47 |
| FatPhil | My GPU is powered up .4%, and in RC6 99.6% of the time | 15:47 |
| FatPhil | I'd rather just spin the fan up! | 15:48 |
| FatPhil | that's what it's there fore! | 15:48 |
| FatPhil | -e | 15:48 |
| gnarface | hmm, is this nvidia gpus? | 15:48 |
| gnarface | the nouveau drivers are known for failing to spin up the fans sometimes | 15:48 |
| gnarface | even their official drivers screw it up occasionally | 15:49 |
| gnarface | worth trying a different version | 15:49 |
| FatPhil | lspci says we have different Intel VGA controllers, I'm not sure if that identifies the GPUs | 15:50 |
| gnarface | does vga only show up once? | 15:50 |
| gnarface | yes, but there could be more than one of them, in theory... | 15:54 |
| gnarface | maybe not with an old thinkpad | 15:54 |
| gnarface | there's two different xorg drivers you could be using though | 15:54 |
| gnarface | the default modesetting one and the one actually called intel | 15:54 |
| gnarface | you know we're in #devaun-arm though right? | 15:55 |
| gnarface | *devuan | 15:55 |
| FatPhil | oooops! I must have accidentally changed window | 16:00 |
| FatPhil | -> offtopic | 16:00 |
