So I played writing values into all other registers with i2cset, but with little success - not any change, actually, except for the mentioned register. Ok, and you could block off the screen as well by disabling the sync pulses (not much of a surprise, I guess). However, leaving all that aside - I'm no longer able to talk to the chip, upon rebooting i2cdetect gave me all blanks on bus #6. I really wonder what is going on. Could it be that there is some additional "gating" going on that blocks off access to this chip unless another register is set? Is that typical? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
