Assuming the Manjaro Live-USB is running the same version of kernel/modules and firmware, then it is worth checking /proc/config.gz for the running kernel's configuration and comparing it with your gentoo configuration. Also while you're there you could check with lsmod what modules were loaded by the Manjaro kernel to see if you're missing something. Ah, I had gone through that! Looked at almost line by line the two dmesg, lsmod, configs etc. Of course Manjaro's config is big! Turns out there was something in ACPI page of kernel config that did the trick (not sure what exactly to be honest - might be Video). Thanks though!

I've always used system-% use flags for firefox, never had a problem, but yeah things could have changed in this version. Things have definitely changed with this version. From a previous thread on FF 68 posted in this M/L and some experimentation on my systems it seems the way addons are processed in FF 68 could cause FF to barf when being launched. The fact FF works fine when launched with --safe-mode pointed to this and (re)moving addonStartup.json.lz4 fixed the problem here. Did that, no change. I'm also using a fresh profile, so it should exclude things like that. Right now I'm compiling with disabled custom-cflags. Next will be to disable custom-optimization and if those don't help, I'll start disabling system-% flags. I've done an strace and it seems to hang waiting for a futex... So the browser is waiting for some value in memory to change or to be released from some other process before it can be used by FF ... I think. Only problem is each try is gonna take ~5 hours on my poor machine. :-) We'll see! The high CPU could be indicating a graphics issue, where the browser cannot use hardware acceleration for some reason on your system and it falls back on software rendering. It may be worth running some browser rendering tests to confirm this. Well, the browsing itself seems fine (i.e. navigating pages). It's when I use it's UI that I experience these slowdowns. I have disabled custom-cflags & custom-optimization, did a build with clang 8 instead of 7, no change... I've also killed compton, and messed with the browser's acceleration settings with no luck. Next try I'll disable system-libevent & system-sqlite and see what happens... Emmanuel

Re: [gentoo-user] AMD RX GPU in Gentoo
On 17/6/19 2:16 π.μ., mad.scientist.at.la...@tutanota.com wrote: Sadly, in my experience graphics cards draw a fairly steady current independent of usage (it varies a bit, but less than 20%). Some of the newer cards may be better. There are utilities for at least some cards to adjust the clock on the GPU (normally used by mad gamers/miners to overclock). These might be an option, cmos draw power at a rate determined by clock frequency and it's a squared relationship, half the clock speed means about 1/4 the power draw. I would also like to find some low power graphics cards, The only option I'm aware of is to buy older, used cards on ebay. I have a few machines I'd like to run headless most of the time, but basic text or basic graphics would be nice occasionally, but I don't want to waste 200W+ on a high end graphics card that never gets exercised. Other than that, I've used an external 80mm fan to blow air across the heat sink and out the adjacent slot (after the attached fan failed and i removed it. I mounted the fan in the drive cage. The fans on graphics cards are generally moving air the worst way possible (just like many cpu heat sink/fan combos), blasting it into the face of a heatsink at high speed so there is some flow through the channels with massive, massive turbulence/noise. Oddly enough although the built in fan had a tachometer the card doesn't pay any attention to what it thinks is the fan speed, even if the fan stalls completely so you don't have to "fool" the graphics card when removing the provided fan and using an "external" fan. These are very good points, thanks! (Thanks to all btw who replied). Well, the PC is connected to a 1440p monitor, so it's not headless like that, and although it's not that often I fire up Steam, I do have some games to waste time now and then :-) I will research more on power consumption (which goes hand in hand with being cool and silent). From the little I've seen AMD GPUs should have some sort of power management with the AMDGPU driver. Emmanuel "Would you like to see us rule again, my friend? All you have to do is follow the worms."

[gentoo-user] AMD RX GPU in Gentoo
Hi! I'm running a pretty old PC. A Core2Duo E8400 and a GT730 nvidia card. Now, this is ok for what I need: work (emacs and bunch of terminals) and some little Kerbal Space Program. I'm thinking of upgrading some time in the next months to a 3600 AMD Ryzen when they are available, but in the mean time, I was also thinking about changing to an AMD gpu too. The nvidia driver although ok, is giving me some trouble mostly when suspending to ram. Sometimes it wont work, and the culprit from dmesg is likely the nvidia blob. So, assuming I would get an RX550/560 card, how well do the amdgpu drivers (open source) work? Are they ok for steam games? Do they provide KMS (switching to a Ctrl+Alt+F1 is always garbled now). ? Are they completely tear free? Plus, my current GT730 is passively cooled. Are there any RX cards that at least spin down the fans when I'm working on desktop (no plasma/gnome, simple Openbox with no heavy gpu requirements). I really like silence! :-) Thanks, Emmanuel
