similar to: [Bug 73267] New: Nouveau: corrupted laptop screen's EDID info

https://bugs.freedesktop.org/show_bug.cgi?id=34554 Summary: Nouveau seems to have corrupted my laptop screen's EDID info Product: xorg Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Driver/nouveau

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

For an unknown reason both my monitors ended up with a corrupted EDID. They both provide VGA and DVI input. The VGA input works fine, while DVI is broken because of the EDID issue. Using these [1] instructions I have been able to read the EDID and fix it. Unfortunately I'm not able to write it back to the eeprom. I always get this message: i2c i2c-1: sendbytes: NAK bailout. This is what I

Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with hooks to switch DDC, DRM core is amended with a

Commit df8dc97cd17 (drm/nouveau/kms/nv50: use drm core i2c-over-aux algorithm) switched things over to the drm algo. Unfortunately it generates address-only transactions. Prior to GF119, the hardware had no support for such things, and GF119+ the nouveau code did not handle these properly. The result of this bug is that EDID doesn't make it over for DP (and eDP) screens, which in turn wreaks

Are you able to get me new kernel logs of both before and after this patch with "log_buf_len=8M drm.debug=0x14 nouveau.debug=disp=trace,i2c=trace,bios=trace" please? Thanks, Ben.

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

Signed-off-by: Viktor Novotny <noviktor at seznam.cz> --- Hi, I think I found a bug - my NV11 fails to init i2c ports and is then unable to read EDID. It's because while i2c_table in nouveau_i2c.c:324 returns null for this card, i2c is initialized anyway at line 341 and wrong i2c table format is then selected at line 350. This patch fixes the problem on NV11 and was tested also on NV25.

I've been trying to do this for days, and I think I'm really close. It's become one of those so-close-yet-so-far sorts of things.

Hello Tom, I tried the new UPnP support of shorewall, olny to stumble upon a LinuxIGD bug. Specificaly, the UPnP chain is read as UPn from the upnpd.conf . I double checked it, there some bug in the upnpd, it doesn''t process 4 lettered names correctly. Could you change this chains'' name to something a little longer? -- Costas Cavouracis <cca@freemail.gr> My PGP keys:

It looks like that when we moved over to using drm_connector_for_each_possible_encoder() in nouveau, that one rather important part of this function got dropped by accident: /* Right v here */ for (i = 0; nv_encoder = NULL, i < DRM_CONNECTOR_MAX_ENCODER; i++) { int id = connector->encoder_ids[i]; if (id == 0) break; Since it's rather difficult to notice: the
