Check youor mesages and look for EDC asset. There is a fix teed up which may help your case. I have seen this "EDC assert" issue with 8265 [1] and the fix is given in comment #42. I have tested it on kernel 5.2-rc7 and works fine. This impacts all pre-9000 intel wifi cards. This will NOT make it into 5.2, as Emmanual G points out, as its late in the cycle; presumably will be in 5.2.1 and 5.3. A work around you might try is to add this iwlwifi option - then reboot. # cat >> /etc/modprobe.d/iwlwifi.conf options iwlwifi swcrypto=1 regards, gene [1] https://bugzilla.kernel.org/show_bug.cgi?id=203315

That was me. Try the following: set the boot Display to HDMI in the bios / Uefi. If it shows stuff (Lenovo logo or bios menu if invoked) it’s not the hardware. For me the issue fixed itself after a day without explanation. — Flo
Re: [arch-general] External monitors are no longer detected (Intel graphics)
Regarding kernel versions: I also had noticed instabilities (more errors than usual in dmesg from drm and i915, weird GL/compositing glitches) on my HD4400 Intel with one external monitor and laptop display starting with 5.1.x. I've so far remained on 5.0.3 and have not debugged in depth due to a lack of time, but the issues definitely started after 5.0.3.
Re: [arch-general] External monitors are no longer detected (Intel graphics)
There are *some* issues with intel gpu's and recent kernels. I can't use multiple monitors in most of the cases as the i915 module misinterpret possible resolutions, for example. Also, I remember some issue with external monitors on this list not long ago: https://lists.archlinux.org/pipermail/arch-general/2019-June/046539.html Even if the OP suspected a faulty HDMI port, this might still be related.
Re: [arch-general] External monitors are no longer detected (Intel graphics)
Have you checked the troubleshooting options on https://wiki.archlinux.org/index.php/Intel_graphics. I also recall an intel issue with recent kernels, but can't put my hand on a link. The problems experienced with some are listed in the wiki. There are *some* issues with intel gpu's and recent kernels. I can't use multiple monitors in most of the cases as the i915 module misinterpret possible resolutions, for example. https://bbs.archlinux.org/viewtopic.php?id=246230 https://bugzilla.redhat.com/show_bug.cgi?id=1570392 https://intel-gfx-ci.01.org/cibuglog/open_bugs.html I'm stuck on aur/linux-lts49 on my Zotac CI547 in the meanwhile as everything works there. But better than nothing - or 1024x768 ;) Thanks guys. The wiki doesn't list my exact issue, so I'll try booting into linux-lts when I get home and see if that helps. Cheers, Bennett

[arch-general] External monitors are no longer detected (Intel graphics)
Hi, I'm using a Thinkpad T450s with Intel graphics. Yesterday, I could no longer connect external monitors via miniDP. They were not detected at all, either by xrandr in i3 or by sway (wayland). I didn't have time to dig out a VGA cable and try that, so I cannot rule out physical damage yet - I did try 2 monitors with different cables, both of which work with my wife's Thinkpad. Since wayland doesn't make a difference, I'm thinking maybe something broke with the (my?) drivers? Is there any other possibility apart from physical damage, and what do I try next? Cheers, Bennett
