15:50DottorLeo: hi!
15:58DottorLeo: Venemo: hakzsam: dschuermann: mareko: bnieuwenhuizen: I hope you will enjoy the GFX7 card for your tests :)
15:59hakzsam: yeah, thanks a lot
19:44rah: I have a new 4k 144Hz monitor and I'm trying to get X to use refresh rates higher than 60Hz but having no luck
19:45dwfreed: what card, what connection method
19:45rah: RX 480, DisplayPort
19:45rah: ~$ xrandr -q | grep 3840x2160.*120 && xrandr --verbose --output DisplayPort-0 --rate 120.02 && xrandr -q | grep 3840x2160.*120 3840x2160 60.00*+ 119.91 120.02 96.02 72.02 60.01 50.01 48.00 99.90 79.95 60.00 50.00 59.94

19:45rah: ooof, line endings messed up
19:46dwfreed: use a pastebin, that's unreadable
19:46rah: ~$ xrandr -q | grep 3840x2160.*120 && xrandr --verbose --output DisplayPort-0 --rate 120.02 && xrandr -q | grep 3840x2160.*120 3840x2160 60.00*+ 119.91 120.02 96.02 72.02 60.01 50.01 48.00 99.90 79.95 60.00 50.00 59.94

19:47rah: argh
19:47rah: https://paste.debian.net/1307561/
19:47HdkR: Looks like it sees 120hz at least
19:47HdkR: amdgpu kernel module has issues seeing 144hz for some displays
19:48rah: dmesg shows nothing, /var/log/Xorg.0.log shows nothing and xrandr reports nothing
19:48rah: how can I determine why nothing's happening?
19:49rah: HdkR: I'm not trying to set it to 144Hz, I'm trying to set it to 120(.02)Hz
19:50rah: I'm telling xrandr what refresh rate to use and it doesn't produce an error but also it nothing changes
19:50rah: s/also it/also/
19:51HdkR: `drm.debug=0x4` kernel argument theoretically should enable some additional logging
19:53Remco: Which exact 480 do you have? Not every version might have the same ports
19:55dwfreed: try 119.91
19:57rah: I tell a lie, it's an RX 460
19:57rah: XFX Radeon RX 460 Heatsink Edition
19:57rah: Remco: what do you mean by "ports"?
19:59Remco: Sometimes manufacturers put on lower quality connectors (displayport/hdmi) to save a bit of money
20:00rah: Remco: I'm confused; how is that relevant?
20:00Remco: That would mean it has a harder time syncing
20:00dwfreed: 4k 120 is close to the upper limit of DP 1.4
20:02dwfreed: so if you can't get full DP 1.4 speeds, due to poor quality connection, then you won't be able to actually use 4k 120
20:24rah: adding "drm.debug=0x4" to the kernel command line produces nothing when running xrandr
20:26rah: rah@lotus:~$ xrandr --output DisplayPort-0 --rate 72.02 && echo yes
20:26rah: yes
20:26rah:boggles
20:31rah: it'll do 2560x1440@120Hz no problem
20:35HdkR: It's weird since you would expect a dmesg about link training failure or the likes
20:48rah: it's not getting as far as trying to train the link
20:48rah: nothing happens
20:48rah: at all
20:48rah: the screen doesn't go blank and come back
21:23_ds_: Does the monitor have an option to display the frame rate?
21:38rah: yes, it doesn't differ from what "xrandr -q" reports
