emrge --info
I've tried ~amd64 gentoo-sources-4.6.3, but the problem is still there. The hardware is working : I have just tested with a live-usb of xubuntu 16.04 and it works well. Not really sure who the best assignee is here, trying kernel and x11. can you try UXA instead of SNA? Or the modesetting driver instead of xf86-video-intel? I am sorry, but as I could'nt find any way to make it work, and I needed my computer to be functionnal, I had to wipe out my 12 year old gentoo install. I am now using Debian. Ok, marking as resolved then. If you decide to install Gentoo again and encounter this bug, you can reopen it with the requested information. |
Created attachment 439468 [details] dmesg Hello, I am using a dual screen setup, the main screen connected to DVI output, the secondary screen connected to VGA output. I am using in-cpu graphics. The secondary screen is (physically) rotated by 90° I just upgraded my system by replacing motherboard (Asus B150M-C with the latest bios available : 1801), RAM and CPU from sandybridge to skylake (i7-6700), and recompiled the kernel to fit my new hardware. The secondary screen is no more working as expected : instead of displaying the desktop, it is black and only shows the mouse pointer if it goes in it. If I rotate it back to horizontal state, the dual screen works well. dmesg gives a lot of stack traces (attached file) xrandr : Screen 0: minimum 8 x 8, current 2970 x 1680, maximum 32767 x 32767 DP1 disconnected (normal left inverted right x axis y axis) DP2 connected 1050x1680+0+0 right (normal left inverted right x axis y axis) 465mm x 291mm 1680x1050 59.95*+ 1400x1050 59.98 1280x1024 75.02 60.02 1440x900 59.89 1280x960 60.00 1152x864 75.00 1024x768 75.08 70.07 60.00 832x624 74.55 800x600 72.19 75.00 60.32 56.25 640x480 75.00 72.81 66.67 60.00 720x400 70.08 HDMI1 connected primary 1920x1200+1050+0 (normal left inverted right x axis y axis) 582mm x 364mm 1920x1200 59.95*+ 1600x1200 60.00 1680x1050 59.88 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.08 60.00 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08 HDMI2 disconnected (normal left inverted right x axis y axis) HDMI3 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) emerge --info is also attached.
