Description of problem: Runlevel 3 tty display shows brighter lines after 5-7 lines of display. Splash screen shows darker at the top than at the bottom as well. Version-Release number of selected component (if applicable): coreutils-8.24-6.fc23.x86_64 How reproducible: randomly. Steps to Reproduce: 1.see description 2. 3. Actual results: see description Expected results: see description Additional info:
How is this related to the coreutils package? How are you confirming this is a software problem at all?
Kamil, Thanks for your response. 1) I believe that the tty binary comes from core utils. Yes? 2) the problem comes and goes, and has crossed Fedora version boundaries... even with different hardware. Thanks, George...
Kamil, How can you just close this bug without even waiting for my information?

I have not closed the bug. Anyway, I fail to see how the issue could be related to the tty binary. It is just a utility that prints name of the terminal connected to standard input. Please provide details about your HW, kernel and the graphics driver in use.
Kamil, You raise an interesting point. I had assumed that this was the device driver for the device. Let me see under which circumstances I get this behavior. It just might be a specific piece of software using the device. I'll post here if/when I find something. I jumped to the conclusion that since this bug is listed as "NOTABUG" below with a "resolved as" status, that you had closed the bug. I apologize for the misfire. Thanks for your help and time.

I agree with Kamil - I don't see any connection with tty utility - although it can't be ruled out. I think terminal is more likely than coreutils - what terminal do you use? We can reassign it there, as terminal maintainer may have other ideas how to better debug this issue.
Ondrej/Kamil, Thank you so much for your help. I use Konsole about 99% of the time and was not able to produce the problem with the various utilities I use (more/less/cat/vi) although I think I've seen it with the boot console and the virtual consoles (i.e., ctrl-f2). I was able to create the problem with xterm though but the characteristics of the problem are different. I'm not sure just where this one should go. Again, thanks for your help AND time, George...
Just to be clear, you have tried different physical displays and it had no impact on the issue, right? I see you have two graphics cards installed. Could you please check which of them is used when the problem occurs? Have you tried to switch the primary display to the other graphics card?
Kamil, 1) right. 2) I'm not sure how to tell which card is in use. I would presume that the Nvidia card is for the laptop screen since this is a "gamer" laptop so the Samsung is the other card. Yes? 3) I only use the Samsung Let me try switching to the laptop display as primary. I'll report here. Again, Thanks, George...
(In reply to George R. Goffe from comment #9) > 2) I'm not sure how to tell which card is in use. For Xorg, the info should be available in /var/log/Xorg.0.log. I am not sure about the native tty, probably the output of dmesg should give some hints. > I would presume that the > Nvidia card is for the laptop screen since this is a "gamer" laptop so the > Samsung is the other card. Yes? Samsung? I though the other graphics card was Intel.
Kamil, You're right... I chose the wrong word. Intel -> Samsung. After some testing I have discovered software that changes the "brightness" of the tty or whatever I'm using. It's a full screen editor. I'm trying to contact the maintainer. The problem appears EVERYWHERE. Thank you so much for all your time and patience with me. This bug can be "really" closed. Thanks again, George...
Ok, thanks for information, closing NOTABUG based on that.
