Compared to e.g. CentOS before 7, or indeed any other Linux/Unix system where vnc is completely under user control? I have always run an instance of vnc-server for each user. I never gave the user control, just assigned the port number for the user. I have been doing this at least since CentOS4. Now the fun comes in as to what GUI you are using. The install is for Gnome, and if you want any other GUI, you have work in front of you. I have it working for Xfce. I have a separate systemd service file for each user. And I enable them all, just the way I run things. I suppose there are ways you can have the user start his specific systemd service from their ssh shell. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] Cgroups : memory.limit_in_bytes and memory.usage_in_bytes includes file cache?
Hello All, We were under the assumption that Cgroups memory controller, limits memory based on just the RSS size of the process. However, i see that the process is getting killed even when the RSS size is very low compared to the limit in bytes. For example: cat memory.stat cache 85880266752 rss 2441216 rss_huge 0 mapped_file 8192 swap 0 pgpgin 29265847812 pgpgout 29244880354 pgfault 48530374728 pgmajfault 20 inactive_anon 0 active_anon 2441216 inactive_file 85879496704 active_file 770048 unevictable 0 hierarchical_memory_limit 85899345920 hierarchical_memsw_limit 85899345920 total_cache 85880266752 total_rss 2441216 total_rss_huge 0 total_mapped_file 8192 total_swap 0 total_pgpgin 29265847812 total_pgpgout 29244880354 total_pgfault 48530374728 total_pgmajfault 20 total_inactive_anon 0 total_active_anon 2441216 total_inactive_file 85879496704 total_active_file 770048 total_unevictable 0 cat memory.usage_in_bytes 85885800448 cat memory.limit_in_bytes 85899345920 What is confusing is that , why is memory.usage_in_bytes being shown as 85885800448, when the RSS is just 2441216? Is it true that memory.usage_in_bytes/memory.limit_in_bytes takes files cache into consideration when calculating the usage?

[CentOS] upgrading 7.5 ==> 7.6
hI ALL! There have been a large enough number of people posting here about difficulties when upgrading from 7. to 7.6 that I'm being somewhat paranoid about it. I have several machines to upgrade, but so far the only one I've dared to work on (least critical if it goes bad) is my new-to-me-but-used laptop. First I did a 'dd' backup of the whole drive onto an external USB drive then did the upgrade. Since I use the Mate desktop, I enabled the epel testing repo (per postings on Mate troubles at the time of the upgrade). Result: Boots to GDM just fine, but Mate is a black screen. Switching to Gnome, works fine, but I can't stand Gnome. Not knowing what else to try I restored the dd backup. Later I inserted a spare HD and did a new install from the DVD media. This installed without issue, but now no desktop works. Switching to a console (CTRL-ALT-F2) I did a full "yum update", which installed quite a few packages, but upon reboot nothing had improved. So I added the epel repo (and testing) and installed Mate. Ditto, nothing had changed. This laptop is fairly old, and according to lshw, has a RV635/M86 [Mobility Radeon HD 3650]I] video chipset, in case it matters. CPU is identified as: Intel(R) Core(TM)2 Duo CPU T9400 @ 2.53GHz Having previously installed 7.5 on it without trouble, on which Mate works just fine, I wonder what could have become so broken that neither an upgrade nor a fresh install works. I have, as I said, several other machines to upgrade, too, some of them have Nvidia grahics (esp. my main desktop box, which also uses Linux software RAID-1) and all run Mate. Then there is a netbook (low priority) a couple of VMs (in virtualbox) and at work several other VMS as well as bare-metal on a Lenovo deskside machine, and I'm afraid to do an update on all of them because I need them to be in usable condition. The Lenovo box in my office is somewhat urgent, as I am about to retire and turn it over to someone else who doesn't know much about Linux. I'd appreciate any advice I can get on how to get these systems upgraded without breaking them. thanks in advance for your help!

No. Users can run vncserver and attach to them like you could before, or you can run Xvnc -inetd, just as a systemd service/socket pair instead of out of xinetd. The black screen problem that you mentioned does sound familiar -- I've seen it with VNC clients that don't support OpenGL, with the GNOME desktop (which uses a compositing display manager), it just crashes when you log in. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] Out of memory
Hi, I have three machines running CentOS 7.6 in desktop mode. 2 are fine. 1 of them is having a memory issue that is Out of memory [17878] 1000 17878 206999142311 118988800 0 gnome-shell This gnome-shell looking at /var/log/messages after reboot - is the HIGHEST amount of memory. Looking at "top" now - it certainly does not use that amount of ram at this time. These are the gnome-shell packages installed. rpm -qa | grep gnome-shell gnome-shell-extension-alternate-tab-3.28.1-5.el7.noarch gnome-shell-extension-top-icons-3.28.1-5.el7.noarch gnome-shell-extension-window-list-3.28.1-5.el7.noarch gnome-shell-extension-launch-new-instance-3.28.1-5.el7.noarch gnome-shell-extension-apps-menu-3.28.1-5.el7.noarch gnome-shell-extension-common-3.28.1-5.el7.noarch gnome-shell-extension-user-theme-3.28.1-5.el7.noarch gnome-shell-extension-places-menu-3.28.1-5.el7.noarch gnome-shell-3.28.3-6.el7.x86_64 Why is gnome-shell eating my memory? What can I do? Basically - the machine isn't even doing anything. Boots up and shows one static web page. At this time that is all. Then about 24 hours later its out of memory. The other 2 machines that seem fine - are showing the same web page. But not out of memory. Thanks, Jerry ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

In this case, there are no user logins on the console, this is meant to be a remote login server. Anyone logging in via vnc gets the black screen treatment. There is no login screen, only the vnc password prompt. For this type of machine, multi-user.target should be sufficient, although it is set to graphical.target right now. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

The user did not have "control" of the sessions. Do you get a login screen? Does the screen go "black" after login? If so, in my experience, the user logging in already has a desktop session running (usually on the console). Make sure to try logging in with a user that is not already logged in. Linux can deal with multiple DIFFERENT users logged in but the desktops can only deal with one login and home directory per user.

[CentOS] VNC question
We have run into the infamous black screen problem with tigervnc under CentOS7, which prompted me to look into how vnc is configured here. https://access.redhat.com/solutions/966063 Am I reading this correctly - root needs to set up a systemd vnc service for every user and display individually? Compared to e.g. CentOS before 7, or indeed any other Linux/Unix system where vnc is completely under user control? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
