https://bugzilla.kernel.org/show_bug.cgi?id=102931 Christian König changed: What|Removed |Added CC||deathsimple at vodafone.de --- Comment #4 from Christian König --- get-edid calls into the BIOS directly to access the I2C bus and doesn't uses the driver. With a kernel driver this is pretty much deprecated and shouldn't be used any more. Use the one provided in sysfs instead, try: find /sys -name "edid" -- You are receiving this mail because: You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=102931 Alex Deucher changed: What|Removed |Added CC||alexdeucher at gmail.com --- Comment #1 from Alex Deucher --- IIRC, get-edid doesn't actually probe any i2c buses, it uses vm86 to do vbe calls to the vbios. vbe will only provide the edid for whatever monitor it happened to probe at boot and likely won't work correctly once a real driver is loaded. It's also not multi-head aware so if you have multiple monitors attached or are using a different display than what was available at boot it probably won't work. -- You are receiving this mail because: You are watching the assignee of the bug.
