What was your last RTFM adventure? Tinker this, read that, make something smoother! Or explodier.
As for me, I wanted to see how many videos I could run at once. (Answer: 60 frames per second or 60 frames per second?)
With my sights on GPUizing some ethically sourced motion pictures, I RTFW, graphed, and slapped on environment variables and flags like Lego bricks. I got the Intel VAAPI thingamabob to jaunt by (and found that it butterized my mpv videos)
$ pacman -S blahblahblahblahblahtfm
$ mpv --show-profile=fast
Profile fast:
scale=bilinear
dscale=bilinear
dither=no
correct-downscaling=no
linear-downscaling=no
sigmoid-upscaling=no
hdr-compute-peak=no
allow-delayed-peak-detect=yes
$ mpv --hwdec=auto --profile=fast graphwar-god-4KEDIT.mp4
# fucking silk
But there was no pleasure without pain: Mr. Maxwell F. N. 940MX (the N stands for Nvidia) played hooky. So I employed the longest envvars ever
$ NVD_LOG=1 VDPAU_TRACE=2 VDPAU_NVIDIA_DEBUG=3 NVD_BACKEND=direct NVD_GPU=nvidia LIBVA_DRIVER_NAME=nvidia VDPAU_DRIVER=nvidia prime-run vdpauinfo
GPU at BusId 0x1 doesn't have a supported video decoder
Error creating VDPAU device: 1
# stfu
to try translating Nvidia VDPAU to VAAPI – of course, here I realized I rtfmed backwards and should’ve tried to use just VDPAU instead. So I did.
Juice was still not acquired.
Finally, after a voracious DuckDuckGoing (quacking?), I was then blessed with the freeing knowledge that even though post-Kepler is supposed to support H264, Nvidia is full of lies…

and then right before posting this, gut feeling: I can’t read.
$ lspci | grep -i nvidia

SO. What was your last RTFM adventure?
Couldn’t get the geolocation work for weeks in openSUSE. I, supposedly, read the manual and checked everywhere and even asked in the opensuse forum, since the timing was perfect with Mozilla shutting down MLS, and it probably was a reason, but also any other alternative didn’t work. Some days ago I decided to RTFM of geoclue again, only to find out that I could just “hardcode” my location in an /etc/geolocation file >:(
For me, it was getting a handle on rsync for a better method of updating backup drives. I was tired of pushing incremental changes manually, but I decided to do a bit of extra reading before making the leap. Learning about the -n option for testing prior to a sync has saved me more headaches than I’d care to enumerate. There’s a big difference between changing a handful of files and copying several TB of files into the wrong subfolder!
Oh I love the “walk me through what I’m about to do” concept. Dry runs should be more common – especially in shell scripts…
The world would be a better place if every install.sh had a --help, some nice printf’s saying “Moving this here” / “Overwrite? [Y/N]”, and perhaps even a shoehorned-in set -x.
Hope your r/w wasn’t eaten up by the subfolder incident (that I presume happened) :P
Not my last, but after using killall in Linux, I tried it on hpux, only to discover and later confirm in the man page that on hpux it doesn’t take any arguments, it just kills every process.
Hardware related on a Linux home built NAS.
My mobo has 2 nvme ports and supports 10th and 11th gen intel cpu. I have a 10th gen i5 and 2 nvme ssd for cache.
The biggest 512Gb ssd is on the front (normal) side of the mobo, under a heatsink. The smaller 128Gb is under the mobo, inaccessible once fixed onto the case.
In bios and in OS I can’t see the 512 cache drive, only the 128. Quick RTFM on the motherboard manual states: “Front nvme slot only works with 11th gen cpu”.
FFS 🤦♂️
The server is fully built in a hard to fit everything ITX case.
Guess who is having only 128Gb cache instead of disassembling everything ?
Wanted to see if I could do anything exciting with the new Satisfactory dedicated server API. There’s no documentation of it anywhere online, but there’s a random markdown file documenting it in the installation directory. Got it working but turns out it can’t do much. Oh well
