[Bug 1165965] Re: External display stopped working
Christopher M. Penalver: I note you write "not filing a new report would
delay your problem being addressed as quickly as possible". As a metter
of interest, how do you define "quickly as possible"?
** Tags added: saucy
** Description changed:
After upgrading to 13.04 beta, my external monitor is no longer
detected/driven. This works perfectly under 12.10, and is therefore a
major regression impacting common use cases.
When the Display Port/VGA adapter is plugged in dmesg reports 15 instances of:
[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up
Hardware: MacBook Air 2012
Display configuration: Apple Display Port to VGA adaptor
Ubuntu version: 13.04 beta.
