The nvidia driver for linux prevents from using any non-native resolution : https://devtalk.nvidia.com/default/topic/525287/linux/non-native-resolutions-not-available-in-3xx-drivers-on-8700m-gt/ In Jogamp, the result is that : - monitor modes listed are limited to native resolution - fullscreen seems to be limited to native resolution However, note that on the very same computer, most games ( from steam, for instance and probably not jogamp games) gives the possibility to choose from plenty of screen resolution. As stated in the link at the top, it's seems to be related to xrandr.
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.

@Maxime: I need more input to validate this NV driver issue.
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. Exectuing the same test cases as yours leads to a different result for me : Screen: NEWT-Screen[.x11_:0-1-s0, idx 0, refCount 1, vsize [ 0 / 0 1920 x 1080 ], X11GraphicsScreen[X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x7f82d8003640, owner true, ResourceToolkitLock[obj 0x23006ff2, isOwner false, <67cea89c, 309fcf02>[count 0, qsz 0, owner <NULL>]]], idx 0], NEWT-Display[.x11_:0-1, excl false, refCount 1, hasEDT true, edtRunning true, X11GraphicsDevice[type .x11, connection :0, unitID 0, handle 0x7f82d8003640, owner true, ResourceToolkitLock[obj 0x23006ff2, isOwner false, <67cea89c, 309fcf02>[count 0, qsz 0, owner <NULL>]]]], monitors: [Monitor[Id 0x0, 344 x 193 mm, viewport [ 0 / 0 1920 x 1080 ], orig [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr], curr [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr], modeChanged false, modeCount 8]]] All-0[000]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr] All-0[001]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 90 degr] All-0[002]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 180 degr] All-0[003]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 270 degr] All-0[004]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 0 degr] All-0[005]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 90 degr] All-0[006]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 180 degr] All-0[007]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 270 degr] All-1[000]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 270 degr] All-1[001]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 180 degr] All-1[002]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 90 degr] All-1[003]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 0 degr] All-1[004]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 270 degr] All-1[005]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 180 degr] All-1[006]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 90 degr] All-1[007]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr] 0: Monitor[Id 0x0, 344 x 193 mm, viewport [ 0 / 0 1920 x 1080 ], orig [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr], curr [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr], modeChanged false, modeCount 8] [00][000]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr] [00][001]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 90 degr] [00][002]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 180 degr] [00][003]: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 270 degr] [00][004]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 0 degr] [00][005]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 90 degr] [00][006]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 180 degr] [00][007]: [Id 0x2df, [ 1920 x 1080 x 32 bpp ] @ 50.0 Hz, flags [], 270 degr] [0] orig : [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr] [0] current: [Id 0x2de, [ 1920 x 1080 x 32 bpp ] @ 60.0 Hz, flags [], 0 degr] _____________________________________________________________ It's confirmed by the xrandr output : maxime@W520:~$ xrandr Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 1920x1080 60.0*+ 50.0 DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) DP-4 disconnected (normal left inverted right x axis y axis) DP-5 disconnected (normal left inverted right x axis y axis) _____________________________________________________________ As stated in my first message, using --q1 allows to see that multiple resolution are handled : maxime@W520:~$ xrandr --q1 SZ: Pixels Physical Refresh *0 1920 x 1080 ( 341mm x 190mm ) *50 51 1 1680 x 1050 ( 298mm x 185mm ) 52 2 1440 x 900 ( 255mm x 158mm ) 53 3 1366 x 768 ( 242mm x 135mm ) 54 4 1280 x 1024 ( 227mm x 180mm ) 55 5 1280 x 800 ( 227mm x 141mm ) 56 6 1280 x 720 ( 227mm x 127mm ) 57 7 1024 x 768 ( 181mm x 135mm ) 58 8 800 x 600 ( 142mm x 105mm ) 59 9 640 x 480 ( 113mm x 84mm ) 60 Current rotation -

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 ..

(03:14:07 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 ..

(03:17:00 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.
