Description Devin Reade 2010-05-13 04:59:14 UTC
Created attachment 413630 [details] dmesg output Description of problem: RHEL6.0 beta install on a Lenovo Thinkpad T500 (discrete graphics mode). If the text console is showing (via ctrl-alt-F2) and the machine is left idle for a while, the screen blanker kicks in. However, when a key is kit thus causing the login prompt to become visible again, the display is set to its dimmest setting. Using the thinkpad keys to increase the display brightness has no effect while in text mode. Using alt-F1 to go back to graphics mode, the graphics screen is at its dimmest setting as well. Once in graphics mode, the thinkpad keys can be used to increase the brightness again. In gnome-power-manager for AC power (where this occurs), the box "Dim display when idle" is NOT checked and "set display brightness to" is 100%. (For battery power, "dim display when idle" is checked.) If the system is in graphics mode when it goes idle and the display is blanked out, then it is at the proper brightness when a key is pressed. Let me know what other diags are desired. (dmesg attached) Version-Release number of selected component (if applicable): gnome-power-manager-2.28.2-2.el6.x86_64 How reproducible: Steps to Reproduce: 1. Ctrl-alt-F2 to get to text login prompt 2. Let the system go idle. The screen will blank 3. Touch a key. The screen will unblank but will be very dim Actual results: on return from idle, the display is set to its dimmest setting Expected results: on return from idle, the display should be at the original brightness

Also when you try to adjust brightness back to normal in login screen it does not work. It works after logging in. T400 with discrete graphics, ati mobility radeon hd 3470.

This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. **

Yeah it is still an issue with beta2refresh
Comment 7 RHEL Program Management 2011-04-04 01:51:04 UTC
Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
Comment 8 Richard Hughes 2014-05-20 08:45:40 UTC
The brightness is not supposed to be changed when sitting on a different VT. Can you do something like this and post the logs please: (in vt7, i.e. X) killall gnome-power-manager gnome-power-manager --verbose Then switch to vt1, wait for the bug, then post the complete logs. Thanks.
Comment 9 gingerling 2016-06-16 10:37:46 UTC
think I have this, my brightness keeps going down to zero and staying there
