03:05 <Doliometer> Glanzmann, thanks for the suggestion. I installed fvwm (replacing blackbox) and added the key statements to the default config file. Now the screen will blank after inactivity but not wake up completely, instead returning to the very dim state first observed. Also strange: my brightness controls, F1 and F2, have no effect.

05:39 <Glanzmann> Doliometer: In order for it to work, you need to install sudo (apt-get install sudo) and configure it to let your user to commands as root without password prompt: visudo and add the following line to the bottom: username ALL=(ALL) NOPASSWD: ALL

05:39 <Glanzmann> My sudoers looks like that, my username is 'sithglan': https://pbot.rmdir.de/3e1fdlNLA59BMaEhLGdI7A

05:40 <Glanzmann> Also make sure that you have 'light' installed: apt install -y light

05:40 <Glanzmann> Let us knwo if it works for you.

08:19 <ahdeb[m]> just adding a user to the sudo group is easier and safer than editing the sudo configuration... su -c adduser foobar sudo

08:20 kode54 has quit [Quit: Ping timeout (120 seconds)]

08:21 kode54 has joined #asahi-alt

08:21 <mps_> hm, on alpine I solved this by adding normal user to video group, not need for sudo

08:27 <ahdeb[m]> cy8aer: debian.net is not official debian infrastructure. Any DD can request and redirect/reconfigure hosts on debian.net for any purpose. Also http.debian.net used to be a DNS RR/geodns service but had many problems and was shut down many years ago... it has since been pointed to deb.debian.org which is fastly CDN. Just use deb.debian.org directly instead.

09:40 <jannau> Doliometer: it is a strange bug in the DCP firmware. It doesn't happen on all devices. previous brightness is only restored ~3 minutes after powering the display off

09:41 <jannau> there are workarounds for that in place but those don't work reliable on X11

10:48 <mps_> kallisti: download this file http://dl-cdn.alpinelinux.org/alpine/v3.15/community/aarch64/ovmf-0.0.202011-r1.apk

10:48 <mps_> untar it with tar

10:48 <mps_> and you will find 'usr/share/OVMF/QEMU_EFI.fd' file

10:49 <kallisti> ok

10:49 <mps_> move QEMU_EFI.fd to your working dir

10:49 dgb has quit [Quit: dgb]

10:50 <mps_> and then try as root or with sudo this https://tpaste.us/QNVb script

10:50 <mps_> I'm going to prepare black tea now

10:51 <kallisti> mps_: thanks. I will give it a shot. Should be under 5 minutes.

10:52 <mps_> ncopa: fyi, we lost ovmf pkg in latest release

10:52 <cy8aer> @adheb[m]: Ah thanks for this information. Looks like there is some inflation of deb packages repository cdns. Will use deb.debian.org in future.

10:57 <kallisti> mps_: I am booted into the environment

10:58 <kallisti> -drive if=virtio,id=hd1,format=raw,file=/dev/disk0s6 \

10:58 <kallisti> should I see a device `hd1`?

10:59 swaggie has quit [Remote host closed the connection]

10:59 swaggie has joined #asahi-alt

10:59 <kallisti> I don't see it. But I do see /dev/disks*

11:00 <kallisti> Should I just try mounting disk0s6?

11:00 <kallisti> Think I need to chroot the env

11:02 <kallisti> wrong, I was looking in the wrong terminal. I don't see the /dev/disks* devices

11:02 <kallisti> ir gd1

11:02 <kallisti> *or hd1*

11:06 <kallisti> [ 0.375889] virtio_blk virtio3: [vda] 105192 512-byte logical blocks (53.9 MB/51.4 MiB) [ 0.377398] vda: vda1 vda2 vda3 [ 0.378271] virtio_blk virtio4: [vdb] 959631360 512-byte logical blocks (491 GB/458 GiB)

11:08 swaggie has quit [Ping timeout: 480 seconds]

11:09 <kallisti> So assume I just need to mount vdb and passwd --root MOUNT_POINT USER_NAME

11:09 <mps_> kallisti: so you booted it?

11:09 <kallisti> yeah i am booted into it. Those are dmesg lines above

11:10 <mps_> yes, vdb should be you asahi partition

11:10 <kallisti> yeah it says mounted in dmesg or whatever but i don't see that via mount

11:11 <mps_> cat /proc/mounts

11:13 <kallisti> I mounted it manually

11:13 <kallisti> seems to have mounted

11:13 <mps_> so, last thing is to change password

11:15 <kallisti> yeah, it looks like it doesn't support the --root parameter

11:15 <kallisti> so I can't set the mount directory as root to change the password

11:15 <mps_> yes, it is busybox passwd applet

11:16 <kallisti> So then I assume I actually need to chroot into the environment to change it

11:16 <mps_> I don't have idea, I always change password with VI editor

11:18 <kallisti> ? like edit /etc/passwd?

11:19 <mps_> 'root::19344:0:::::' in my /etc/shadow :)

11:20 <kallisti> ls -halt /media/vdb/etc/shadow* -rw------- 1 root root 741 Dec 4 07:24 /media/vdb/etc/shadow -rw------- 1 root root 741 Dec 4 07:24 /media/vdb/etc/shadow-

11:21 <kallisti> seems to be two of them

11:21 <mps_> this with '-' at end is backup

11:22 <kallisti> Ok. Then I guess I'm just going to wipe out whatever looks like a hash. looks like there are two of them.

11:23 <mps_> in shadow file second field is hashed and salted password

11:23 <kallisti> so if I wipe them out, then I will just be able to login without a password?

11:24 <mps_> kallisti: yes, if your distro does not try to be smart

11:24 <kallisti> it's the asahi default -> arch linux arm

11:24 <mps_> never tried to install it

11:25 <kallisti> Looks like some users are like usbmux:!*

11:25 <kallisti> perhaps no login?

11:26 <mps_> yes, forbidden login

11:26 <kallisti> Looks like some users are like usbmux:*

11:26 <kallisti> and some without either

11:27 <mps_> kallisti: https://linux.die.net/man/5/shadow

11:27 <kallisti> well guess i'm ready to write it and try to reboot and see if I can login

11:28 <kallisti> thanks for the help mps_ . I will give that a shot and come back and let you know if it worked.

11:28 <mps_> so 'root::............' should allow paswordless login for root

11:29 <mps_> not blindly as I typed it

11:29 <mps_> I mean, second field is empty

11:30 <kallisti> I just tried to wipe my user account

11:30 <kallisti> don't think i had a root password set

11:30 swaggie has joined #asahi-alt

11:30 <kallisti> right well time to give it a shot

11:30 <kallisti> brb

11:30 <mps_> ok, good luck

11:30 kallisti has quit [Quit: brb]

11:36 kallisti has joined #asahi-alt

11:36 <kallisti> mps_: looks like the password reset worked. Thank you kindly for all the help!

11:37 <mps_> kallisti: np, you are welcome

11:38 mps_ is now known as mps

11:39 <mps> ncopa: ok, found it, it is renamed to aavmf

11:40 <mps> and don't see it in release notes

11:40 <kallisti> heading out. it's almost 4am here. I'll come back again and reach out then.

12:20 <Glanzmann> mps: with the latest mesa changed mpv -vo gpu improved a lot for me.

12:20 <Glanzmann> When I use compton I also don't have tearing with my worst video https://tg.st/u/man_over_bord_small.mp4

12:22 <mps> Glanzmann: yes, also with '-vo=gpu-next' it is better

12:23 <Glanzmann> mps: For me it is worst with -vo=gpu-next.

12:23 <Glanzmann> worse*

12:23 <Glanzmann> At lease with my test video.

12:25 <Glanzmann> Also something seems to change regarding dcp performance.

12:25 <Glanzmann> Previously when I resized windows it was very slow. But that problem is also gone.

12:25 <Glanzmann> Only thing that still gives me trouble is xfreerdp. It is very slow and sometimes don't draw areas of the screen.

12:28 swaggie has quit [Ping timeout: 480 seconds]

12:31 <mps> Glanzmann: hm, so we have opposite with gpu-next, interesting and I have no idea why

12:32 <Glanzmann> mps: Have you tried playing https://tg.st/u/man_over_bord_small.mp4

12:32 <Glanzmann> Is this fast for you with mpv -vo gpu-next?

12:32 <Glanzmann> If so, then I'll compile the most recent mpv and try again.

12:33 <mps> Glanzmann: yes, it tears with gpu

12:34 <Glanzmann> mps: For me with compton in fullscreen, I don't see tearing.

12:34 <Glanzmann> However if I put a window in front, or I have the mpv controlls layed over or if I play in a video it is okay.

12:35 <Glanzmann> mps: But with -vo gpu it is now using only 250% CPU before it was almost 800%.

12:35 <mps> for me works fine with -vo xv and x11

12:35 <Glanzmann> With -vo gpu-next it is back to 800% CPU for me.

12:35 <Glanzmann> mps: Yes, that worked fine for me before as well. However with the lastes mesa updates, no -vo gpu improved a lot as written by alyssa.

12:35 <mps> hm, I see new commits in mesa, maybe should rebuild now

12:36 <Glanzmann> I had a bug in my mesa build script so it fetched the newest release but did not check it out. I just fixed that. So I ended up always building the same mesa version ...

12:37 <Glanzmann> ahdeb[m] / Doliometer I also added my user to the group 'video' that way I no longer need the sudo for 'light'.

12:38 <mps> now building mesa again, will rerun tests in a minutes

12:38 <Glanzmann> mps: Let me know.

12:39 <mps> sure

12:39 <Glanzmann> ahdeb[m]: Is there a debian infrastructure ready to use that creates a fresh build root for building every package? So that the build environment only contains the base packages + the build deps of the package I'm building?

12:46 <mps> Glanzmann: ah yes, it is now a lot better with -vo=gpu

12:48 <mps> and now gpu-next is worse

12:49 <Glanzmann> Yep. Same for me.

12:50 <Glanzmann> mps: Also the resizing of windows in Xorg has improved a lot. But I don't know since when. Maybe it was a mesa change or gpu change that I did not notice.

12:51 <mps> Glanzmann: resizing window was always fine for me

12:51 <mps> could be because I don't use any borders or decors for windows

12:52 <mps> ok, there were for few days lag with one of DCP/DRM versions

12:52 <mps> lag when maximizing windows

12:53 <Glanzmann> mps: Yep. This is waht I meant. It is gone for me now.

12:53 <Glanzmann> xfreerdp is also more usable with: xfreerdp /u:Administrator /p:'Pa$$w0rd' -grab-keyboard /cert-ignore /f /bpp:32 /v:localhost:4000 -gfx /rfx

12:53 <mps> it's gone for me with first gpu version I tried

12:53 <Glanzmann> So the last two options '-gfx /rfx' improve it a lot. But I still sometimes have screen arefacts.

12:54 <Glanzmann> mps: Interesting. For me it is gone only very recently. Maybe it were the gpu changes marcan did in the last stream. No idea.

12:54 <Glanzmann> But since I have not pulled a new kernel it needs to be something related to mesa.

12:55 <mps> (don't force me to go back ;) )

12:58 <Glanzmann> I won't. :-)

17:28 <Doliometer> Glanzmann, thanks for response. My username is in the sudo group. No problem there. I've installed "Light" now, and a superuser can control screen brightness. I have yet to untangle permission settings so that a user can use F1 and F2 to affect screen brightness.

22:38 <ahdeb[m]> glanzmann: sbuild is used by official debian buildd for clean chroots. I personally use pbuilder because of old habits and it (atleast in a decade old past) was easier.

22:40 <ahdeb[m]> there's also git-buildpackage which can use cowbuilder (or sbuild too I assume) behind the scenes.
