Dear Nouveau developers, I encountered this problem using Artix Linux: https://forum.artixlinux.org/index.php/topic,5859
On 2 laptops (Dell M4400 and M4500, Nvidia graphics using Nouveau) which have a VGA port, a Maxim MX11-LCD15 TV with a VGA port stopped working, also another Panasonic TX-26LXD500 TV using VGA. These are older TV's, from the 2000's, I guess the EDID might not be entirely compliant with modern standards. A newish AEC monitor (not TV) did work with the latest kernels so not all VGA connected monitors are affected. >From searching online it seems that there are numerous reports of monitors >stopping working with the 6.2 kernel in various distros. This is the commit where the problem apparently first appears: https://cgit.freedesktop.org/drm-intel/commit/?h=drm-intel-fixes&id=f530bc60a30bee47ff51b7fb71511fdd058b774a commit f530bc60a30bee47ff51b7fb71511fdd058b774a (HEAD) Author: Ben Skeggs <[email protected]> Date: Wed Jun 1 20:46:33 2022 +1000 drm/nouveau/disp: move HDMI config into acquire + infoframe methods v2: - fix typo in sorhdmi/g84 struct initialiser (kbuild test robot) v3: - less convoluted flow control in nvkm_uoutp_mthd_acquire_tmds() (lyude) v4: - we don't support hdmi on original nv50, don't try Signed-off-by: Ben Skeggs <[email protected]> Reviewed-by: Lyude Paul <[email protected]>
