Q4OS 5 for Raspberry Pi

NoMoreWindows · 2024-03-11 20:50

Sorry if this goes off topic, but might this be related to my keyboard delay issue? Someone reports a similar issue a few days ago.

https://forums.debian.net/viewtopic.php?t=158515

I have a 3440x1440 resolution screen which is common for both main PC and Pi system (dual HDMI input). I'll test with other monitors tomorrow.

Update 18/04/2024: the keyboard problem disappeared as mysteriously as it came on both systems...

Q4OS on Rasperry Pi is very close in my opinion. We have this errorcode:80 problem on the Q4OS installer, and the unwanted keyboard configuration screen while booting. That’s all I’ve found.

This is an important feedback for us. We are just working on fix for "errorcode 80" bug.

We don't think so.

The keyboard configuration screen coming up during boot is also a real issue (I’ve sent a screen shot by mail). Here are the step that lead up to the issue (probably not much to do about it but I give them anyways).

After the succesfull “Full profile” install I had been using the system for some hours.
Then decided I wanted Bluetooth and succesfully installed Blueman. It asked for a reboot.
During that reboot the boot stopped on the keyboard configurator screen.
I wanted to get out by choosing “<Ok>”.
It then came on a screen asking to create a user.
After that the boot process stopped on a command prompt from which I have no idea how to continue the boot into the graphical environment.
After power OFF/ON I end up again at the boot prompt.
So I know nothing better to do than to run the imager again on the SD to start again from scratch.

This is the second time that this happens so it is certainly something that will happen to others and must be repeatable although I cannot give you steps to repeat yet. I’ll let you know when I have.

NoMoreWindows · 2024-03-12 08:21

I didn't experience the keyboard delay issue on the second installation from scratch. I hope/think it's not an general issue with this Q4OS for Pi. But I'll certainly let you know when it happens again.

Apart from the few problems it is a pleasure to work with Q4OS on the Pi. I almost forget I'm not on my main PC. But as I said, on my system browsing with Firefox is somewhat slow and video playback only works well in low resolutions <=360p. Can someone confirm these limitations?

We confirm this bug. We consider it as a critical one and will work on a fix certainly.

Yes, we have received the e-mail. You could also attach files to any of your post here.

Please keep detailed reporting if possible, it's truly helpful for investigations.

Yes there is some speed drop on the Pi, it would be interesting to compare Q4OS with plain Raspbian installation.

I can install the plain Raspbian on another pi 4 and try to compare performances. Never installed the 32bits version on a pi 4, only used 64bits versions (because performances are said to be better), will try it and report.

I'll wait for seb3733's conclusions but I've tried PiOS32 bit, PiOS 64bit and Q4OS Pi32bit from the same SD.

I see a difference between 32 and 64 bit systems. (64bit is better)

64bit runs Firefox 10-20% smoother. 64bit runs a 720p video with VLC full screen without problems, 32bit Q4OS struggles, even hung up my system when I wanted to leave full screen.

I assume Q4OS and Pi OS perform the same with 32bit.

Not sure what happened here, VLC runs fine now on Pi OS 32bit.

q4osteam · 2024-03-12 16:33

Well, VLC on PiOS/32bit plays video fine while Q4OS struggles. So it looks we only need to install some package/s to enable acceleration as Q4OS is PiOS with some additional packages actually.

Yes, I think too there's a problem with the video acceleration, although there's supposed to be a performance difference between 32bits and 64bits versions, this shouldn't be so huge (we must be able to read 720p youtube video without any problems, 32 bits or not; the pi4 is designed to output to 2x4k displays...)

q4osteam · 2024-03-13 10:22

A short summary of bugs we are currently investigating and working on fixes:

- critical - keyboard config shows at boot in console , see https://www.q4os.org/forum/viewtopic.ph … 353#p26353

- debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable - is dpkg-reconfigure process blocking ? see https://www.q4os.org/forum/viewtopic.ph … 329#p26329

- Vlc struggles to play videos while Pios goes fine - ? install some package to enable acceleration

Suggestions, findings, reporting, comments would be appreciated.

NoMoreWindows · 2024-03-13 23:15

Unfortunately we have to deal with the performance limitations of the Pi itself. I wonder if there is a light weight browser that would perform without hesitation on the Pi.

But it is very nice to have the ease of use, software catalog and customizations options of Q4OS on Pi. For a light weight system the Debonaire theme for example looks very good to me.

I don’t have access to my Pi for the next days so I’ll probably only will start testing again on Monday. Good luck with the fixing, looking forward to it.

We should be able to use chromium, it seems one of the problems now is the graphical accelleration; I noticed some artefacts when resizing or moving windows when using gl compositor, a symptom of a graphical acceleration problem I think.

For the moment I didn't try any performance tweaks (because we need something stable first, and we are testing), but I think there's room for improvements (and raspberrys can be easily overclocked too).

I tried my windows10 theme and it's working like a charm too

I have a very good general feeling about it, it's very promising, and it's a pleasure to have Q4OS and its features on a raspberry. I just bought a Pi 5 two days ago, it's on its way, can't wait to test Q4os on it (and will report of course)

I have a Rpi 3B+ runing with Raspberry Pi OS. For the moment I don't want to change the OS, but I just want to mention that I also had problems with Chromium: I use my pi remotely with VNC Viewer and, that way, Chromium window is filled with black and white stripes. Maybe this confirms your suspicions.

Instead I have installed Firefox, which works well with 1 GB total RAM (I don't use it to look at videos nor other "heavy" task).

@All
We are working on fixing bugs and getting close to a new release. We would need some debugging information. It would be really useful to get the command output from both Q4OS and Pios-32bit:
$ sudo raspinfo
It is important to run it from graphical desktop environment, i.e. logged into Trinity(Q4OS) or LXQt(Pios). If possible, please provide it.

Nice! I'll provide requested info this evening.

18:30 I've sent the file to develop@q4os.org, did not see how I could attach more than one file here.

here it is for q4os raspberry, will install classic pi OS 32bits tomorrow and give you the results
Edit: it seems Nomorewindows was faster than me

@seb3773
Thanks, we've already received the debug files from @NoMoreWindows . We are now finishing new testing release, so we will need more debug files from the new version.

Ok ! Ready for that, I have now one sdcard with Pi OS and another one for Q4OS raspberry, this will be easier

Downloaded, booted, installed Full Profile. Looking good so far. Was Firefox intentionally left out?

What I'm missing is lag free internet browsing, but that is probably too much too ask from the Pi 4's hardware. VLC playing 720p video is OK now.

I'll have my fun trying it the following days. Thanks!

Yes, it's easily installable:
$ sudo apt install firefox
We will add Firefox into the Software center list too in the next release.

Keep in mind, this is still a testing release.

No worries, I'm aware it's a test version.

Just wondered if you considered Chromium a better choice on the Pi. Midori isn't faster either as far as I can see.
It's not that browsing is awful. I'm approaching this as a naive user and so far this is the only remark I have. (That there is some lag browsing the internet.)

Pi 4 is not really intended to be a full blown desktop PC. But it is certainly fun to try to get that kind of performance out of it.

seb3773 · 2024-03-21 14:47

Testing the last version, so far so good, no bugs encountered yet, reactivity seems a bit better.

About the chromium youtube playback, I did some tests on Pi OS 32bits, and it seems the performance is somewhat similar to q4os version. (~720p ok, but beyond is a problem). This is not a problem with q4os raspberry, it's the same with Pi OS, and a lots of posts on https://forums.raspberrypi.com/ are refering to that. Didn't know that, as I always worked in terminal with raspberrys machines... The Pi4 can display 1080p flawlessly, but only in vlc or other video players. Youtube seems to be problematic, I'm trying now some flags, but I don't expect miracles. Some says that firefox does play youtube videos better, need to try too.

Apart from that, the overall impression is very good. Libre Office is clearly usable, normal browsing a bit slow, but not slower than my old Celeron N3060 laptop I'm trying other apps too, everything seems to be working ok.

I can't wait to test it on my Pi 5 (on its way ), I think with the additional cpu performance this will be like the "real" desktop experience.
But, I think it's already very good with the pi4. It will be very interesting for schools for example
