executing xrandr --output LVDS --left-of VGA disables the LVDS if VGA is connected. I can check with i810switch that LVDS is being deactivated through that command. Reactivation of LVDS works only through i810switch, xrandr --output --LVDS --auto doesn't work. Interesting enough, KDE and xfce4 think that there is a second monitor left-of the VGA, which makes them put all the applications to the black internal display of my monitor.

Created attachment 13856 [details] Xorg.0.log with intel module from git (2.2-branch) and xserver-xorg from debian unstable (7.3+10), debug-mode
Also tried with xf86-video-intel from git - same problem, see attached Xorg.0.log
Hong/Zhenyu, any idea?
I've seen you have configured the LVDS to be left-of VGA in xorg.conf, is it OK when X startup? and it only happens you execute the command? Could you elabrate on what steps you have done to trigger this bug? Thanks, Hong
Hi Hong, no, it doesn't work even at startup - only the external monitor is working (of course LVDS works if the external monitor is not connected). I didn't do a lot to trigger the bug: I upgraded from i810 to intel in xorg.conf and changed xorg.conf to what I posted above (I also tried to delete xorg.conf). The options --left-of and --right-of (in xorg.conf or with xrandr) make kde think the desktop is bigger (applications and the mouse disappear to the (black) LVDS) but LVDS doesn't show a picture. What I can sometimes realise when executing xrandr --output LVDS --left-of VGA, is that LVDS changes a little bit the light, the black gets a little bit lighter. That made me already think that there is some screensaver-function or powersafe on the LVDS. But then I realised, that i810switch shows me, that lcd is off! I can turn it on with "i810switch lcd on", but that gives me only a clone of VGA and it will be again "off" when I execute afterwords xrandr --output LVDS --left-of VGA again. I tried with different kernels (debian lenny standard kernel and my own 2.6.22 kernel), I tried with the xserver-xorg-etc.-packages from debian unstable, experimental and from git, no change. Probably the output of xrandr -q --verbose (after startup with the posted xorg.conf, no other xrandr or i810switch commands executed) might be interesting for you: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 768 VGA connected 1024x768+0+0 (0x4e) normal (normal left inverted right) 304mm x 228mm Identifier: 0x4c Timestamp: -1510538410 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 EDID_DATA: 00ffffffffffff0026cd483811050000 1c0c01036c1f1778ea0430a2564b9d25 105054afce0001010101010101010101 01010101010164190040410026301888 360030e410000018d50980a0205e6310 1060520830e41000001a000000fd0038 4b1f3c08000a202020202020000000fc 004158333831385554432020202000f4 1024x768 (0x4e) 65.0MHz -HSync -VSync h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.4KHz v: height 768 start 771 end 777 total 806 clock 60.0Hz 1024x768 (0x4f) 78.8MHz +HSync +VSync h: width 1024 start 1040 end 1136 total 1312 skew 0 clock 60.1KHz v: height 768 start 769 end 772 total 800 clock 75.1Hz 1024x768 (0x50) 75.0MHz -HSync -VSync h: width 1024 start 1048 end 1184 total 1328 skew 0 clock 56.5KHz v: height 768 start 771 end 777 total 806 clock 70.1Hz 1024x768 (0x4e) 65.0MHz -HSync -VSync h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.4KHz v: height 768 start 771 end 777 total 806 clock 60.0Hz 800x600 (0x51) 50.0MHz +HSync +VSync h: width 800 start 856 end 976 total 1040 skew 0 clock 48.1KHz v: height 600 start 637 end 643 total 666 clock 72.2Hz 800x600 (0x52) 49.5MHz +HSync +VSync h: width 800 start 816 end 896 total 1056 skew 0 clock 46.9KHz v: height 600 start 601 end 604 total 625 clock 75.0Hz 800x600 (0x53) 40.0MHz +HSync +VSync h: width 800 start 840 end 968 total 1056 skew 0 clock 37.9KHz v: height 600 start 601 end 605 total 628 clock 60.3Hz 800x600 (0x54) 36.0MHz +HSync +VSync h: width 800 start 824 end 896 total 1024 skew 0 clock 35.2KHz v: height 600 start 601 end 603 total 625 clock 56.2Hz 640x480 (0x55) 31.5MHz -HSync -VSync h: width 640 start 656 end 720 total 840 skew 0 clock 37.5KHz v: height 480 start 481 end 484 total 500 clock 75.0Hz 640x480 (0x56) 31.5MHz -HSync -VSync h: width 640 start 664 end 704 total 832 skew 0 clock 37.9KHz v: height 480 start 489 end 491 total 520 clock 72.8Hz 640x480 (0x57) 25.2MHz -HSync -VSync h: width 640 start 656 end 752 total 800 skew 0 clock 31.5KHz v: height 480 start 490 end 492 total 525 clock 60.0Hz 720x400 (0x58) 28.3MHz -HSync +VSync h: width 720 start 738 end 846 total 900 skew 0 clock 31.5KHz v: height 400 start 412 end 414 total 449 clock 70.1Hz 640x350 (0x59) 25.2MHz -HSync +VSync h: width 640 start 656 end 752 total 800 skew 0 clock 31.5KHz v: height 350 start 387 end 389 total 449 clock 70.1Hz LVDS connected 1024x768+0+0 (0x4e) normal (normal left inverted right) 0mm x 0mm Identifier: 0x4d Timestamp: -1510538410 Subpixel: horizontal rgb Clones: CRTC: 1 CRTCs: 0 1 1024x768 (0x4e) 65.0MHz -HSync -VSync h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.4KHz v: height 768 start 771 end 777 total 806 clock 60.0Hz 1280x768 (0x5a) 80.1MHz h: width 1280 start 1344 end 1480 total 1680 skew 0 clock 47.7KHz v: height 768 start 769 end 772 total 795 clock 60.0Hz 800x600 (0x53) 40.0MHz +HSync +VSync h: width 800 start 840 end 968 total 1056 skew 0 clock 37.9KHz v: height 600 start 601 end 605 total 628 clock 60.3Hz 640x480 (0x5b) 25.2MHz -HSync -VSync h: width 640 start 656 end 752 total 800 skew 0 clock 31.5KHz v: height 480 start 490 end 492 total 525 clock 59.9Hz This output is still the same after "i810switch lcd on" as well as after "xrandr --output LVDS --left-of VGA" All that made me think that i810switch must be deactivating something else then xrandr can do...

Hi Hong, I tried the patch. Now I get a clone of VGA on LVDS (with the unchanged xorg.conf), but no left-of. Executing xrandr --output LVDS --left-of VGA again disables LVDS, only that I can reenable it with xrandr --output LVDS --auto, which didn't work before. See attached Xorg.0.log. Greetings, Ben

Does the rightof option in Xorg get correct at X server startup? And after you enable LVDS with xrandr, LVDS+CRT display correctly (i.e a 2048x768 screen)? Thanks, Hong
Could you please attach the register dump log after you executing xrandr --output LVDS --left-of VGA? There is a tool in our driver package (xf86-video-intel/src/reg_dumper/intel_reg_dump). Thanks, Hong
Created attachment 13997 [details] [review] i830 dvo fix 2nd Please try this patch. And if there still has problem, please provide log I asked in comment #9 and #10. Thanks, Hong
Hi, First to your questions about the first patch: KDE startet with a clone on LVDS and CRT, not taking care of the "right-of" option in xorg.conf. Resolution was correctly 1024x768 on both screens (not 2048, which I declared only for the virtual screen). I applied the second patch (on a clean git clone without the other patch). Again, kde starts with a clone on VGA and LVDS (with a correct resolution of 1024x768), even if the "right-of" option ist activated in xorg.conf. xrandr --output LVDS --left-of VGA changes the virtual screen but not the visible: LVDS and VGA keep showing the same image, but cursor can be moved to the invisible screen. Same for xrandr --output LVDS --right-of VGA. After that I executed xrandr --output LVDS --off, which switches LVDS of and virtual screen is only the size of one screen again. (i810switch still reports LVDS to be "on", which might be the correct behaviour?). I can switch LVDS on and off now with --off and --auto, but --left-of and --right-of doesn't change anything if LVDS was turned of with xrandr --output LVDS --off. So far, I can't compile the reg_dumper utility. It fails with the folling messages: /home/bve/bin/xf86-video-intel/src/reg_dumper/main.c:45: undefined reference to `pci_system_init' /home/bve/bin/xf86-video-intel/src/reg_dumper/main.c:52: undefined reference to `pci_device_find_by_slot' /home/bve/bin/xf86-video-intel/src/reg_dumper/main.c:56: undefined reference to `pci_device_probe' /home/bve/bin/xf86-video-intel/src/reg_dumper/main.c:72: undefined reference to `pci_device_map_range' collect2: ld returned 1 exit status make: *** [intel_reg_dumper] Fehler 1 Greetings, Ben

It's expected behavior, commands only be effective when output is on.

Would you please execute the left-of command just after X startup (no other commands in between) and attach the log? Thanks, Hong

Created attachment 14033 [details] intel_reg_dumper output after --left-of after startup Hi, as you suggested, I executed xrandr --output LVDS --left-of VGA just after startup. The result is that the virtual screens for KDE seems to know a second screen on the left (the mouse can go there), but both screens show a clone of the right part of the virtual screen.
Something else I now realized, which could be related: xrandr --output LVDS --off dectivates correctly LVDS, while xrandr --output VGA --off deactivates both the external and the internal screen.

Hi Hong, it seems to work correctly now! Thanks a lot for your fast and great work. I have a dual screen now, can switch each output on and off, left-of works with the start of X, I can change everything with xrandr. Also, xrandr -q now shows no more 1280x768 as supported resolution for LVDS, which cannot work on that display. Greetings, Ben
The fix is not in git afaics, so reopening.

Thanks, Hong
*** Bug 11148 has been marked as a duplicate of this bug. ***
From Ben: Works well with only the last patch. If I add both patches, I get a strange behaviour on the VGA, where the drop-down menus are broken if (see screenshot). With only the last patch, I can see no problems so far. I can run xrandr, switch on and off VGA or LVDS, position left-of and rigth-of. So the i830-dvo-fix-2nd patch is not needed.

Ok, I'm closing this one out then. Fix is in commit 975d7833bc844485c7043538336bddcba7f7f90e. We can keep 14570 open a bit longer since Hong might find a better way of doing this (sounds like external displays are still broken somehow anyway).
