TOSHIBA TV screen is `DP1'.
So, to play my 5 cents here perhaps it might be related to the fact this controller supports DisplayPort 1.2 only (Thunderbolt alternate mode from June 2015) which is not that much popular. See [1]. [1] https://en.wikipedia.org/wiki/USB-C#Alternate_Mode_partner_specifications Thank you for the report. Several remarks. 1. If you publish the Dell service tag, all people can look up the system configuration and warranty and so on. No idea, if only that data is needed to get the Dell support to do something. 2. Do you know if it’s X.Org server/Wayland related? 3. Could you please try to build drm-tip? [1] 4. You might also want to join #intel-gfx on irc.freenode.net. Maybe folks in there might help you too. [1]: https://01.org/linuxgraphics/documentation/how-report-bugs The following “warnings” are shown for the module in your log. [ 1.866459] i915: unknown parameter 'enable_rc6' ignored [ 1.866462] Setting dangerous option enable_fbc - tainting kernel [ 1.866464] i915: unknown parameter 'semaphores' ignored Hi, I'm totally new on the forum but I experienced same issue as on attached screens. In my case the problem disappear after some random time (15 sec, 15 min or 30 min). Here is a link do short video, it disappears after about 15 seconds and everything looks perfect. https://drive.google.com/open?id=1V9FknPxg55LU3PhFUiBJb2STMcq42-sg Laptop: Dell XPS 9370 TV with wrong colors: Samsung 48" Smart Hub (UE48H6400) Adapter: Hama USB-C Adapter for HDMI Created attachment 141324 [details]
The colors fix themselves

Please note, that this is about the Linux kernel driver. Looking at your video, it looks like you use Microsoft Windows?

Hi, it is Manjaro OS: Manjaro 17.1.12 Hakoila Kernel: x86_64 Linux 4.18.6-1-MANJARO Uptime: 3m Packages: 1226 Shell: bash I have exactly the same setup, with KDE desktop environment as you do. Might not be a coincidence ... Sorry Paul Menzel, I didn't have enough time to compile a kernel. (In reply to Jules Samuel Randolph from comment #10) > Sorry Paul Menzel, I didn't have enough time to compile a kernel. We didn't have enough time to look at the bug. :p Seriously, we could use feedback running drm-tip. Dropping the "ReadyForDev" tag as we don't have dmesg log from drm-tip yet Jules, can you reproduce this issue with latst drm-tip and send dmesg from boot with kernel parameters drm.debug=0x1e log_buf_len=4M?? https://cgit.freedesktop.org/drm-tip Jules, any updates with drmtip? I'm running out of time friends! I'll try at some point in December. (In reply to Jules Samuel Randolph from comment #15) > I'm running out of time friends! > I'll try at some point in December. Any updates? Jules, do you still have the issue with latest drmtip? If not this bug can be closed. No feedback from more than two months, closing as resolved works for me. Please re-open if issue persists with latest drm-tip https://cgit.freedesktop.org/drm-tip and send dmesg from boot with kernel parameters drm.debug=0x1e log_buf_len=4M? |
