Re: Bullseye unable to select monitor refresh rate

I have just tested the +rpt12 release and it works perfectly on the 7 modes that my monitor supports that require refresh to 3 decimal places, if I were you I would have the next couple of days off :) Thank you very much for resolving this so quickly and I hope you enjoy your well deserved weekend....

Re: Bullseye unable to select monitor refresh rate

Having been swearing at this all day, I have got something which I think will do the right thing more often. (I suspect there will still be cases where it doesn't work, but they will hopefully be relatively rare - certainly it will work correctly on a lot more fractional refresh rates.) It should be...

Re: Bullseye unable to select monitor refresh rate

No problem - and thanks for the offer to test. Looking further into this, the fix is not going to be as trivial as I had hoped - the screen config tool only reads the output of xrandr to determine available modes, so it only has the 2dp version; I am going to need to cross-reference against the outp...

Re: Bullseye unable to select monitor refresh rate

The Screen Configuration tool appears to truncate the refresh rate to two decimal places. For my monitor the correct frequency at 3440x1440 is either 59.973Hz or 29.993Hz. These figures get truncated to 59.97 and 29.99 respectively so when mutter tries to select the chosen refresh it receives an in...

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

No, it won't - they still set resolution in the old way, so this bug will not affect them. This is purely a "feature" of mutter, which uses its own internal version of xrandr and ignores any xrandr setting made at startup. It has not been an entertaining thing to get working, and I am baff...

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

No, this problem wouldn't appear in buster - this is all caused by the way mutter configures monitor resolution, which is completely different from how it was done in openbox, and is ridiculously finicky; various values all have to match exactly in very specific ways. Thanks for confirming the fix -...

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

OK, many thanks for that. Bleagh - there is something really weird happening in the way your monitor reports its status, and I think that is causing the problem; it returns the data I need split across two different data blocks rather than all in one single one, so pulling out the bit I need may be ...

Hi- Clean upgrade of Bullseye here and I'm having the same problem after update and full-upgrade. LG 4k monitor set to 2560x1440 in Screen Configuration, reboot, and comes up as full 4k. xrandr reports 3840x2160 even tho Screen Configuration reports 2560x1440.

I'm having a similar problem with Bullseye and I happened upon this thread while searching for a solution. And, I also have a Samsung TV so I may be able to provide a second data point. Similar to the other person, my TV remains at it's native 4K resolution no matter what I put in /boot/config.txt....

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

Yes, but with a caveat, the current set resolution survives reboots but if you change resolution afterwards then it's back to the start. eg if you change to 1920x1080 and stay with it everything's fine, but if you subsequently switch to another resolution a reboot goes back to I presume native reso...

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

Excellent! I thought it probably would, so I've already made the mods to the screen config tool. Just before I release a fix - to double / triple check, it was the *first* suggestion which worked - so 0x01000e00 is the one to use?

OK, many thanks for doing all the testing - I now see where things are going wrong; your Samsung TV is not reporting a serial number in a format which the window manager recognises.

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

I don't think it is your switch - on looking at it again, it seems that there is a missing field in the EDID data from the parser, which means the correct value can't be set in the monitor config. Can you please try one more thing? Try changing the monitor data in monitors.xml to <monitorspec> <conn...

Re: New Raspberry Pi OS 32bit Cannor Change Resolution

OK, yes, that does help - many thanks. For some reason the serial number from your monitor is not being loaded correctly into the monitors.xml file, which is why the configuration isn't loading. But the serial number is correct in the dump from edid-decode. I'll have to try and work out what might b...

And also the contents of the file /home/pi/.config/monitors.xml after you have tried to set a resolution with the Screen Configuration tool?

Many thanks.

First off - we really do not recommend doing this, and we don't support it! The only recommended way to upgrade to bullseye is to download and flash a clean bullseye image, and transfer your data and applications across. But if you really want to try to upgrade an existing buster image to bullseye, ...

Re: after update to bullseye,D1 resolution setting is broken

The resolution setting option in raspi-config doesn't work with the KMS video driver in bullseye.

You'll need to use the xrandr command-line tool to set resolution instead.
