Re: [Bug 1088992] Re: Sony backlight brightness controls not working in 12.10
Hello. I have updated to the latest BIOS release for my machine, but the screen brightness still does not change when I use the brightness controls (the onscreen brightness slider moves, but the actual screen brightness does not change). The output from the dmidecode command is; R0170D6 03/13/2012 Regards, David Peck. On 9 August 2013 03:23, Christopher M.

[Bug 1088992] Re: Sony backlight brightness controls not working in 12.10
I have installed and tested the v3.7 kernel as requested. Unfortunately the v3.7 kernel does not fix the problem and it makes Unity fail to load. With no additional kernel command line parameters Ubuntu boots, but when it gets to the point where the Unity login screen should appear all I get is a blank orange screen, no cursor and no mouse pointer and from here I can only power the machine off by holding down the power button for 5 seconds. If I add the nomodeset kernel command line parameter then Ubuntu boots and drops to a terminal session where I can log in, but not start the X-server (it reports no screens present). I'm not sure where I should be adding the 'kernel-unable-to-test- upstream' tag. Please advise (I have never raised an Ubuntu bug report before).

Hi Joseph. I don't know if you've seen my update regarding testing of this bug, but if not I've reproduced it below for your reference - I have installed and tested the v3.7 kernel as requested. Unfortunately the v3.7 kernel does not fix the problem and it makes Unity fail to load. With no additional kernel command line parameters Ubuntu boots, but when it gets to the point where the Unity login screen should appear all I get is a blank orange screen, no cursor and no mouse pointer and from here I can only power the machine off by holding down the power button for 5 seconds. If I add the nomodeset kernel command line parameter then Ubuntu boots and drops to a terminal session where I can log in, but not start the X-server (it reports no screens present). I'm not sure where I should be adding the 'kernel-unable-to-test-upstream' tag. Please advise (I have never raised an Ubuntu bug report before). Regards, Dave.
