  • RadeonHD dual screen issue with a Kohjinsha DZ

    You probably heard about the Kohjinsha DZ:



    Well, I'm having some trouble with the dual screen using the RadeonHD driver (the video card is a Radeon HD 3200).

    The extended desktop is ok, but the right screen seems kind of "blur". It's like if some columns where missing.

    See this image: http://nyquil.org/uploads/IndianHeadTestPattern16x9.png
    on the right screen: http://img709.imageshack.us/img709/2240/indiantest.jpg

    Here's a perfect quality DivX: http://img31.imageshack.us/img31/2571/divxy.jpg

    $ cat /etc/services : http://img13.imageshack.us/img13/187...tcservices.jpg

    The problem is exactly the same in clone mode. I tried to plug a screen on the external VGA, it works perfectly (dual screen with the left screen).

    I use X.Org X Server 1.6.5 and radeonhd 1.3.0.

    Here's the xorg.conf file: http://pastebin.ca/raw/1737837
    Here's "xrandr" output: http://pastebin.ca/raw/1732437
    Here's the Xorg.0.log file: http://pastebin.ca/raw/1745723

    Any ideas?

    Thanks.

    Nobody?

    I also tried fglrx, but X freezes at startup.

      You might try the radeon driver (xf86-video-ati). I'd also be curious to see the a copy of the vbios from that device.

        The right screen is detected but stays black with the radeon driver.

        Edit : it seems be blinking sometimes.

            I edited my post just before yours. =)

            I'm using xf86-video-ati-6.12.4

              Any chance you could try xf86-video-ati from git master?

                I just tried it, it does not change anything. :/

                    My bad, I didn't install them properly.

                    So, it's better, almost perfect actually.
                    The right screen is just a little blur. I'm gonna try to take a picture of this.

                    Edit :

                    Well, it's strange. The right screen is blur only on extended desktop mode, not in clone mode. :/

                    Here's the Xorg.0.log : http://pastebin.ca/1767085

                    The xorg.conf didn't change (except the s/radeonhd/radeon/).


                    Re-edit :
                    After some changes with xrandr, the right screen does not seem blur anymore.
                    So thank you very much.

                      Got almost the same laptop, the onkyo dx which has a bit higher res screens, 1366x768 with a similar problem. the bottom screen (right in the expanded configuration) does not come on (no back-lighting).

                      i'm running arch64 with the following relevant packages:
                      stock kernel 2.6.32.7
                      glproto-git 20100206-1
                      libdrm-git 20100206-1
                      xf86-video-vesa 2.2.1-1
                      xorg-res-utils 1.0.3-3
                      xorg-server 1.7.4.901-1
                      xorg-server-utils 7.5-3
                      xorg-utils 7.5-1
                      xorg-xinit 1.2.0-1
                      xf86-video-fbdev 0.4.1-2
                      xf86-video-vesa 2.2.1-1
                      xf86-video-ati-git 20100206-1

                      i used the same xorg.conf with the following mods:
                      1) radeon driver instead of radeon
                      2) 2732x768 virtual screen size

                      after running startx, the LVDS screen is fine (although glxgears indicates only about ~570 fps, that's a problem for another day). i then physically extend the screens and run xrandr:
                      xrandr --output LVDS --auto --output DVI-0 --auto --right-of LVDS

                      as far a x-server goes, it looks like everything is good, the desktop is extended, the mouse pointer moves properly off-screen, but the screen is not lit.

                      the X.log can be found:
                      http://pastebin.ca/1788157

                      Any pointers, suggestions or other requests for other info is greatly appreciated!

                        Did you tried the radeonhd driver?
                        It wrote a page on the Gentoo wiki for the Kohjinsha DZ: http://en.gentoo-wiki.com/wiki/Kohjinsha_Dz, you might be interested.

                          going to give the direct git repository a try later. I do believe the pkgs I'm using are rebuilt nightly from git already. The back-light is off and never turns on. However, running windoze7 turns on both panels.

                          one thing I noticed in your X.log: you are not running KMS and the radeon module since I saw some verbiage about it in the log. Can you confirm this ?

                          :/

                            just recompiled from git and still no luck in enabling the DVI-0 screen back-light.

                            do I have to wait for the next release of the fglrx ?

                            i would be more than happy to do a dump of the vbios in exchange for some help.

                              Are there separate acpi controls for each backlight?
