**** BEGIN LOGGING AT Mon Jan 04 02:59:57 2021 Jan 04 06:41:31 set_: fortunately i had it working using the precompiled linux-image-4.14.108-ti-r131 from repos.rcn-ee.com Jan 04 06:46:36 zmatt: you are correct, installing these packages https://termbin.com/jvbh, their dependencies and a custom compiled version of wayland compositor weston caused kmscube to stop working, without running the compositor, changing any system settings or rebooting. rebooting and reinstalling all the graphics stack packages that enabled kmscube did not help Jan 04 06:48:44 therefore one or more is conflicting with the graphics stack packages, several package names contain the word "mesa", but they don't overwrite any of the graphics library files, and someone else (https://elinux.org/BeagleBoneBlack/SGX_%2B_Qt_EGLFS_%2B_Weston#Compile_Weston_manually) has installed them without breaking kmscube Jan 04 06:50:39 i can start over and try again, but to use a display server, do you know any method to determine which packages are conflicting, so I can edit each one and manually try to fix conflicts? Jan 04 06:52:28 I don't think the debian wayland package works on this stack anyway Jan 04 06:53:35 wiki maintainer claims it did in 2019 Jan 04 06:54:26 ah you're just using the deps, not weston itself.. never mind Jan 04 06:55:39 I dunno, I've never done anything with wayland Jan 04 06:55:54 it's still somewhere on my big to-do list :P Jan 04 06:56:14 we just used sgx with qt5 Jan 04 06:57:40 i installed into /usr/bin weston binaries compiled with custom build options using 4 manually applied and tweaked patches from varying sources, using upstream source obtained this way: git clone -b 7.0 https://github.com/wayland-project/weston.git. no build errors Jan 04 06:58:27 tested kmscube before doing anything else and now get this https://termbin.com/9y1e Jan 04 07:00:18 unfortunately I've been kinda low on energy this weekend so I haven't gotten around to trying stuff with sgx myself :/ Jan 04 07:01:25 on a different system, nothing i know of normally interferes with kmscube executed from tty as long as no display server is actually running. so i can only assume something i did between tests caused this, i.e. simply installing packages and compiling weston. Tested weston afterward, nearly runs but exits with similar error to what kmscube prints now Jan 04 07:01:56 maybe there are ghosts in your system? ;) Jan 04 07:02:03 thats ok, i will keep researching and trying to use things from a backed up debian 10 image with working kmscube Jan 04 07:02:33 time to turn the entire rootfs into a git repo so you can track changes over time ;) Jan 04 07:05:41 wayland was simply my first choice for easy display server for existing gui implementations of my application, looking to the android port for clues I may be able to modify it to use drm directly. that's a good idea Jan 04 07:07:40 i did think over what you said a while back, and i ended up spending a couple days reconfiguring the hardware setup to cut out wifi, so i should be able to use bbb networked with ethernet for the forseeable future Jan 04 08:48:19 found it, ti kmscube depends on ti fork of libgbm from rcn-ee (ti-libgbm2-dev, labelled for stretch). libwayland-egl1-mesa ends up pulling in the debian version of libgbm - if this is installed, at all, bad things happen. so, i'd just need to force install the wayland stack without that dependency, and then make sure build systems send existing gbm.h to preprocessor Jan 04 08:49:18 for now, i don't think i for sure need wayland though, or at least the entire weston (more lightweight options exist) Jan 04 09:25:39 misternumberone: this is why my set of debs included dummy libgbm packages Jan 04 19:17:59 thanks for the idea, i edited your dummy packages and installed them which made using wayland packages easier. Jan 04 19:28:02 however, i've discovered that if the debian package libx11-6 is ever installed, it places a libX11.so.6 in /usr/lib/arm-linux-gnueabihf/. all kmscube binaries, presented with this situtation, actually proceed to call into this library at runtime, which then segfaults. the problem resolves when package removed. I think I can create an automated procedure to programmatically use these phenomena to compile a list of all packages Jan 04 19:28:03 that break kmscube, then check that against the dependencies of any libraries I want to use, but perhaps there exists a more straightforward method Jan 04 19:30:16 it's not all packages whose names contain the phrase "x11" or "mesa", only a few. so, i'd assume there may be many others, like libgbm, yet to be seen Jan 04 22:19:42 misternumberone: weird, I'm pretty sure I've had no problems with libX11 Jan 04 22:23:18 (but that was a long time ago, maybe today I would) Jan 05 00:53:50 set_ I designed a 240W LDO regulator 48V 5A It can dissipate quite a bit of power (20W of power as heat). Jan 05 00:54:24 that's a big LDO Jan 05 01:00:41 Nice! Jan 05 01:01:09 I got pissed on by a dog today right after I got turned down by the girl I like but not before stepping in cat shit. Jan 05 01:01:13 I had a bad day. Jan 05 01:01:15 Sorry. Jan 05 01:01:43 The girl that turned me down owns dogs. One of them pissed on my boot. Jan 05 01:02:18 I tried to get over it. I started to accomplish productivity tasks until cat shit littered my work areas. Jan 05 01:02:20 Blah! Jan 05 01:02:28 Sorry for cussing. Jan 05 01:04:15 Literally, if COVID is caught unto me, I know GOD wants me dead. Jan 05 01:04:38 But back to BBB stuff. Jan 05 01:04:59 So, can this LDO regulator handle up to 500W? Jan 05 01:05:34 And handle regenerative backflow? Jan 05 01:06:34 I found a fellow online at digikey. Jan 05 01:06:54 He seems to think some passives dangling over the side of a switching power supply may be an answer. Jan 05 01:07:13 I really need to learn more first. Jan 05 01:11:12 And yes, that actually did happen to me today. Jan 05 01:11:23 I am feeling like a ball of happiness. Jan 05 01:11:30 "KICK ME!" Jan 05 01:19:19 The one day I remember that was worse went like this...I walked, the rains came, then right when I got near covering, a car drove by and splashed me with about 43.075 gallons of water. Boo! Jan 05 01:19:49 I need more BBB issues. Back to reading. Jan 05 01:20:27 It is like a dang movie. Blah! Jan 05 02:00:40 On a good note, I just saw a meteor. Odd...yes. A good ending to a not-so-perfect day...priceless! Jan 05 02:01:32 You know... Jan 05 02:01:42 Just when things are not going so well, life happens. Jan 05 02:02:00 Or, in this case, rocks. Burning rocks! **** ENDING LOGGING AT Tue Jan 05 03:01:24 2021
