Dear maintainers, I have the same problem here. 2 cards AMD R285X in my PC, black screen after installing the 14.9 fglrx drivers from jessie (the open source default driver works, but I need OpenCl acceleration from fglrx).
I installed the 14.12 drivers from experimental, got the same result. The radeon module is blacklisted properly. I can't see what's wrong. The only suspicious things i can find in the xorg logs are messages like : [ 14.919] ukiOpenDevice: open result is -1, (No such device) [ 14.919] ukiOpenDevice: open result is -1, (No such device) [ 14.919] ukiOpenDevice: Open failed but the initialization seems to continue and ends with these lines: [ 21.794] (II) fglrx(0): EDID vendor "ACI", prod id 6628 [ 21.794] (II) fglrx(0): Using EDID range info for horizontal sync [ 21.794] (II) fglrx(0): Using EDID range info for vertical refresh [ 21.794] (II) fglrx(0): Printing DDC gathered Modelines: [ 21.794] (II) fglrx(0): Modeline "1366x768"x0.0 85.50 1366 1436 1579 1792 768 771 774 798 +hsync +vsync (47.7 kHz eP) [ 21.794] (II) fglrx(0): Modeline "800x600"x0.0 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz e) [ 21.794] (II) fglrx(0): Modeline "800x600"x0.0 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync (35.2 kHz e) [ 21.794] (II) fglrx(0): Modeline "640x480"x0.0 31.50 640 656 720 840 480 481 484 500 -hsync -vsync (37.5 kHz e) [ 21.794] (II) fglrx(0): Modeline "640x480"x0.0 31.50 640 664 704 832 480 489 492 520 -hsync -vsync (37.9 kHz e) [ 21.794] (II) fglrx(0): Modeline "640x480"x0.0 25.18 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz e) [ 21.794] (II) fglrx(0): Modeline "720x400"x0.0 28.32 720 738 846 900 400 412 414 449 -hsync +vsync (31.5 kHz e) [ 21.794] (II) fglrx(0): Modeline "1280x1024"x0.0 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync (80.0 kHz e) [ 21.794] (II) fglrx(0): Modeline "1024x768"x0.0 75.00 1024 1048 1184 1328 768 771 777 806 -hsync -vsync (56.5 kHz e) [ 21.794] (II) fglrx(0): Modeline "1024x768"x0.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz e) [ 21.794] (II) fglrx(0): Modeline "800x600"x0.0 49.50 800 816 896 1056 600 601 604 625 +hsync +vsync (46.9 kHz e) [ 21.794] (II) fglrx(0): Modeline "800x600"x0.0 50.00 800 856 976 1040 600 637 643 666 +hsync +vsync (48.1 kHz e) [ 21.794] (II) fglrx(0): Modeline "1152x864"x0.0 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync (67.5 kHz e) [ 21.794] (II) fglrx(0): Modeline "1280x960"x0.0 108.00 1280 1376 1488 1800 960 961 964 1000 +hsync +vsync (60.0 kHz e) [ 21.794] (II) fglrx(0): Modeline "1280x800"x0.0 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsync (49.7 kHz e) [ 21.794] (II) fglrx(0): Modeline "1280x720"x60.0 74.48 1280 1336 1472 1664 720 721 724 746 -hsync +vsync (44.8 kHz e) Currently, this means my server has just gone as useful as a brick. I'll be happy to help if I can run specific tests on my machine. Best, Pascal
