[Bug 1839544] Re: power setting "display off" maximum is 15 minutes, used to have several hour increment values
This should be a very simple thing to fix. And if I knew "C" I would fix it myself. but I don't, my knowledge base is in many other computer programming languages that date all the way back to the 1960's. While I still program computers, now-a-days they are primarily a tool to be used in solving other problems... In my opinion, the best long term fix would be to provide a "[ ] other" box with a way to allow entering the actual idle time desired -- then a user can set it to what ever their circumstances dictates. unfortunately, The concept of "keyboard idle" is not necessarily the best indication of an "unattended terminal". and the futuristic concept of tracking eyeball movements to see if anybody is actually looking at the screen, would probably not be acceptable to most humans. "15 min" of no keyboard/mouse movement is too short a time period, especially when the screen is being used to display reference material. "never" is too long, especially when you need to keep user specific background processes running - or I would simply logoff and log back on later. (One would hope that the user selectable "idle time" values are being translated internally to some form of seconds or minutes, and that they are not simply used to set a series of "bit switches", thus my suggestion to provide a text entry box.) I would also like to suggest that most folks use a computer to solve real world problems, and that computers exist primarily as a tool to be used, and not just as just programming exercises Thank you. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1839544 Title: power setting "display off" maximum is 15 minutes, used to have several hour increment values To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1839544/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1839544] [NEW] power setting "display off" maximum is 15 minutes, used to have several hour increment values
Public bug reported: Just upgraded to Ubuntu 18.04.2 LTS from Ubuntu 16.04 LTS. In the POWER settings for blanking the display, there used to be several options that allowed selecting a time interval of 1 hour, 2 hours, 4 hours, etc. Under Ubuntu 18.04.2 there are only 9 selectable time values: i.e. 1 min, 2 min, 3 min, 4 min, 5 min, 8 min, 10 min, 12 min, 15 minutes, and never. This might be fine for a portable laptop running on batteries, but is not acceptable for a desktop system. The never option is not good, because then the monitor NEVER goes dark. My preferred time is to set this to 1-hour because of the length of conference calls. It is a real nuisance to have the screen blank on you while you are reading information displayed on the screen to a multi-person conference call... ...Especially if you lock your screen, requiring you to log back on. I suggest adding some of the time values back to the pull down list, or possibly adding a "other" fill-in value box where the user can specify in minutes when he wants the screen to blank when idle. I consider this to be a bug, and not a feature enhancement, because I used to be able to say "1 hour". ** Affects: gnome-control-center (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1839544 Title: power setting "display off" maximum is 15 minutes, used to have several hour increment values To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1839544/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 885989] Re: white screen on second monitor when using two xsessions
I agree with Paul, I do not understand why this still has not been fixed. Multiple screen support worked in Ubuntu 10.04 and 10.10, and does not now work in Ubuntu 11.xx or Ubuntu 12.xx (I am currently on Ubuntu 12.10, would have prefered to stay on 12.04 LTS, but other issues with 12.04.1 forced me to upgrade to 12.10) Since I am accustomed to being able to run separate X screens, (one screen was a single 1024x768, and the other screen was a triple 1440x900) running on a dual head display card) --- being restricted to two SINGLE monitors running in twinview has severely affected my productivity. While I am a software and systems developer, I do not program in C, so I am not comfortable or knowlegable in how to patch files and recompile them under Linux --- and cannot afford to lose my system again for weeks on end like what happened with the upgrade to 12.04.1. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/885989 Title: white screen on second monitor when using two xsessions To manage notifications about this bug go to: https://bugs.launchpad.net/nautilus/+bug/885989/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Dave, Restoring the original libcario module fixed evince --- now NX is unable to display text again. Not being real familiar with the internals of Linux, It never occurred to me to relate the loss of EVINCE with the fix of NX --- especially since they occurried weeks apart from each other. - - - - http://ubuntuforums.org/showthread.php?t=2081746highlight=nomachine I just went out and reread the fix description on NX and found that there are new updates to that report. Originally there were only comments 1 to 5. Now there are comments 6 to 12. apparently other people had the same trouble as I did --- and as I was badly burned by the last attempt to fix NX, I do not want to get burned again. Would you be so kind, as to review those comments and see if there is a recommended fix for NX? As I still consider myself a relatively newbee in Linux, I would appreciate the assistance.)

I went ahead and let to do the install and immediately ran into a number of problems, including the fact that the system would not reboot when the installation was done. All reboot attempts resulted in a black screen. I was able to trace the problem to a missing command in GRUB (I had GRUB 1 with Ubuntu 10.04) After fixing that problem about a week later GRUB was automatically updated to GRUB2. Personally I do not like the UNITY interface, it requires far too many clicks and menu for be to get anything done. I added KDE per recommendations on several of the Ubuntu forums, and that worked for about a week until a MAJOR ubuntu update came thru and messed up KDE. So I uninstalled KDE and tried to use UNITY, but again found it not to my liking. About that time I received an announcement that gnome 3 was available (I do not remeber what the package was called.) I installed that, and started getting a working system again (Took almost 3-4 weeks!!!) After running with the GNOME3 (it always goes into FALLBACK mode, because it thinks my graphics card (EVA nvidia GeForce 9600GTS) is not 3d capable - which it is...) A suggestion was to upgrade once again to 12.10, which I did. Things have been kinda stable since, and have found workarounds for all of the little bugs (like having to run SYSLOG in a terminal screen to get it to work at all, and having to put up with the missing timestamps on each line 'cause they are displayed in white ink, on a white background) I currently log on with GNOME and most things work - except for evince. This is a major problem to me, as almost all of the documentation that I use are in PDF files... After some investigation I found
