Tweak geometry not working

[retrorepair]

I've got an issue where I can't get into the tweak geometry settings to shift the image to the left. Every time I select it, no matter the video backend, I get a black screen and no way to exit so have to reset the machine.

Is this maybe related to the issue from a while ago with exclusive video mode causing a black screen? Although I'm fully up to date and not got this issue with anything else, just the tweak geometry setting.

Does this blackscreen problem only happen with the grid ?

[retrorepair]

Just as soon as I hit the tweak geometry option in gasetup. It doesn't happen with anything else.

I've set a custom arcade_15 preset and reduced the HBP to 6.000 and HFP to 4.000 and games look good, but menus of course are all way over to the right.

can you just exit gasetup, go to the terminal and type grid a,d tell me what is the output ? Simply press ESC to exit

[retrorepair]

That's all I get, it just hangs

[retrorepair]

You can see there I tried to hit escape lol

Have you fully updated ? If yes, please make a support archive and send me the link, thanks

It was up to date a couple of months ago, I'll try to update now though.

I did also notice MAME does the same thing if I have KMS enabled. Works fine using Xorg (even if it's a little epilepsy enducing).

Grid does the same thing with xorg or kms though

You should restore your initial crt_range

Ok, did a full OS update and now nothing runs under KMS. Grid, mame or RA.

Trouble is, after updating I now only get MAME working under xorg, everything else crashes on boot so looks like the update has borked something :(

It's weird because on the first reboot after the update, geometry tweak worked, having rebooted now, i can load attractplus, run MAME roms and anything else just crashes returns me to attractplus (usually without changing resolution back).

Here's the log EDIT, LINK FIXED:

Wish I didn't mess with anything now :(

You should restore your initial crt_range

I tried :(

generic_15 preset ?

[retrorepair]

Yep

Could also try to rollback SDL2 to see if it's that one messing

[retrorepair]

I'm sure you've told me before how to do that but I don't use linux much, how would I do that?

[retrorepair]

Ok, downgraded sdl2 using pacman -U and still the same.

It did ask when updating if I wanted to replace python something with a python like extras/python something, I said yes, maybe I shouldn't have
