In the nvidia forum link, it is suggested the following : ________________________________ " They do provide modes for non-native resolutions. But only to xrandr1.1 and the xvidmode extension. You can see the modes with xrandr --q1 and switch to them with xrandr -s YYYxZZZ " _________________________________ This suggestion is working, it's possible to force the resolution despite it not being listed by the nvidia drive.

Hello Sven, I can provide any needed input. What else do you need ? Hello Sven, I'm working back on trying to find a workaround/solution for this issue.

When an application chooses to use RandR 1.2 requests rather than RandR 1.1 requests, it is assuming control of that configuration and needs to handle all of the options users might want to configure, including scaling." From the previous statement, a posible workaround for this issue could be to force jogamp to use the Randr11 implem rather than Randr13. What do you think of it ? Please note that when using the "Nouveau" driver, everything works as expected, ie all available resolutions are displayed. Copy/paste dialog: (03:11:58 PM) sgothel: just tested .. I see all resolutions (03:12:22 PM) monsieur_max: well, i've tested on a vanilla install of different ubuntu with proprietary nvidia on my computer, no custom changes on xorg.conf, so i'm afraid that this issue might happen for many users (03:12:32 PM) sgothel: Debian Jessie here .. (03:13:00 PM) monsieur_max: interesting (03:13:02 PM) sgothel: Option "RandRRotation" "on" (03:13:02 PM) sgothel: Option "DynamicTwinView" "False" (03:13:02 PM) sgothel: ^^ was required w/ old NV drivers (03:13:14 PM) sgothel: dunno its impact now (03:13:38 PM) monsieur_max: mmmh i'll keep that in mind (03:13:48 PM) monsieur_max: can you teell me your xrandr version please ? (03:14:07 PM) sgothel: sven@risa:~/projects/JOGL/jogl/make$ xrandr --version (03:14:07 PM) sgothel: xrandr program version 1.4.2 (03:14:07 PM) sgothel: Server reports RandR version 1.4 (03:14:31 PM) monsieur_max: ok (03:14:38 PM) monsieur_max: thanks for the information (03:15:29 PM) sgothel: -Dnewt.debug.Screen gives me .. (03:16:06 PM) sgothel: RandR 1.4.0, jogamp.newt.driver.x11.RandR13@6f1fba17 (03:16:06 PM) sgothel: ScreenVirtualSize: 3840x2160 617x339 mm (03:16:06 PM) sgothel: XRRGetScreenSizeRange: 8x8 .. 16384x16384 (03:16:06 PM) sgothel: XRRScreenResources 0x7f21647ec360: Crtc count 4 (03:16:08 PM) sgothel: etc (03:16:45 PM) sgothel: I read NV's response .. a while ago, and they said it's also about the monitor .. i.e. does it support other native resolutions ? (03:17:00 PM) monsieur_max: well, it does :-/ (03:17:47 PM) sgothel: try w/ '-Dnewt.debug.Screen' and above NV settings .. maybe we can solve it finally, I know it's annoying (03:18:41 PM) monsieur_max: using nouveau withtout problem, and mutliple other games are able to switch resolution, also, using xrandr --q1 allows to switch with no problem. No fancy computer Thinkpad W520 (03:19:07 PM) sgothel: yeah .. but its a bit odd to use pre xrandr version .. hmm (03:19:10 PM) monsieur_max: sgothel: ok, I'll get back to you then, I'll update the bug thread with everything soon (03:19:15 PM) sgothel: well, we have both impl. .. (03:19:33 PM) sgothel: if you find a good trigger in code, to switch to old impl. .. hmm (03:19:39 PM) monsieur_max: sgothel: my idea was to force the old one, as a workaround (03:19:44 PM) monsieur_max: yep (03:19:53 PM) monsieur_max: not perfect but good enough (03:20:16 PM) sgothel: try '-Dnewt.test.Screen.disableRandR13' :) (03:20:42 PM) sgothel: x11.ScreenDriver line 93 :) (03:21:07 PM) monsieur_max: haha :) ok noted, unfortunately, I'll have to wait a few hours for that (03:21:24 PM) sgothel: still .. needs a working solution, w/o such magic -Dnewt.test.Screen.disableRandR13 did the trick. All expected modes are available. For me, as it's a nvidia issue, failing to handle xrandr correctly, this is an acceptable solution. Feel free to mark it as resolved. |
