Hi, The HP ZBook 15 G3 laptop builtin display (eDP-1) does not work correctly with v4.11-11413-g2868b25. When booting the laptop, the resolution seems to be limited to 1024x768, and gnome-session segfaults. Up to 4.11 the display works just fine in 1920x1080 mode. I'm seeing this in the kernel logs: nouveau 0000:01:00.0: eDP-1: EDID is invalid: [00] BAD 00 ff ff ff ff ff ff 00 ff

Higher layers tend to add a lot of modes not actually in the EDID, such as the standard DMT modes. Changing this would be extremely intrusive to everyone, so just force the scaler more often. There are no practical cases we're aware of where a LVDS/eDP panel has multiple resolutions exposed, and i915 already does it this way. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110660

Hello * this morning I tried to upgrade from pxelinux 3.11 to 3.84 and discovered that the localboot stuff does not work on HP DL360 G3 and G5. The latest syslinux Version I found with a working localboot is 3.36. pxelinux.cfg/default: default harddisk prompt 1 label harddisk localboot 0 implicit 0 timeout 250 This so simple, it should just work, shouldn't it?

The pre-retina MacBook Pro uses an LVDS panel and a gmux controller to switch the panel between its two GPUs. The panel mode in VBIOS is notoriously bogus on these machines. Use drm_get_edid_switcheroo() in lieu of drm_get_edid() on LVDS if the vga_switcheroo handler is capable of temporarily switching the panel's DDC lines to the discrete GPU. This allows us to retrieve the EDID if the panel

Some notebook systems provide the EDID for the internal panel via the _DDC method in ACPI, instead of or in addition to providing the EDID via DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under the ACPI namespace for each VGA/3D controller, and return the first EDID successfully retrieved via _DDC. Update the i915, nouveau, and radeon DRM-KMS drivers to fall back to

Some notebook computer systems expose the EDID for the internal panel via the ACPI _DDC method. On some systems this is because the panel does not populate the hardware DDC lines, and on some systems with dynamic display muxes, _DDC is implemented to allow the internal panel's EDID to be read at any time, regardless of how the mux is switched. The _DDC method can be implemented for each
