I naively figured that this was the 'default' but alas it is a selection which I did make. I had seen hints of this in discussions elsewhere and did try KDE, but that is tough sledding on C7, and I got impatient. I should have stuck it out. (KDE has a bug on vncserver enable and creates the wrong symlink in /etc. At least it is different and requires work to get it right). Mate is my next try. I did try the nvidia-detect and it did say to use 340.58. Thanks again for helping me converge. I will be silent for a bit to try out different DEs.

Because Gnome3 requires 3D acceleration, and I'm not sure that nvidia driver would simulate 3D stuff in software (nouveau should fall back to mesa in case hardware acceleration fails --- typical of a vnc session). So my suggestion is to try KDE or XFCE or LXDE or Mate or... any other DE which doesn't require 3D features to work. Such DE should work through vnc using nvidia driver no problem --- the only exception is Gnome3. >/ Backed out Nvidia 340.58, back to nouveau, client vnc works again. />/ Also tried 304 driver (only other one in elrepo for el7) - same />/ problem. / You don't want to guess which driver you need.

The open-source radeon driver is much better supported. That said, the radeon community is not any more active or more extensive than the nouveau community. It's just that AMD has released the specs for their cards, so they have a much easier job of maintaining the radeon driver than the nouveau community (which basically needs to RE everything from scratch).

Centos 7 Nvidia openGL breaks vncserver

Another post on this forum suggested to try the Nvidia driver download directly from Nvidia. Better still, I actually had the original NVIDIA-Linux-x86_64-331.49.run file which worked on Centos 6.5. I did a manual install (run level 3 etc). It installed fine. Same problem though. So, at this point it seems associated with the new C7. Either we can hope for a fix in C7, or I will have to try a non-Nvidia card. -------------------------------------------------------------------------------------- Some Background: I learned how to get tigervnc-server working on C7 thru many failed attempts on VMs. I found if I did the following steps exactly, it works. There may be some variability in the sequence that works but I did not try all permutations. But, if I don't do this list exactly, then I would also get the 'oh no ... error at the client. All this to note that getting this to work on C7 with systemd/systemctl is quite sensitive. Steps: Create new VM on hyper-v or kvm (both work fine) Fresh 'DVD' install of C7 1406: both iso file and straight DVD install tried on different VMs. Update software via Software app Install tigervnc-server copy usr/lib/systemd/system/vncserver@:.service to usr/lib/systemd/system/vncserver@:x.service; modified @:x file with user info systemctl enable vncserver@:x.service verify that the vncserver@:x.service symlink is in /etc/systemd/system/multi-user.target.wants/ systemctl start vncserver@:x.service Then go to client and start up vnc ..... ---------------------------------------------------------------------------------------- Stan On 18/11/14 18:32, Stan Cruise wrote: >/ Bare metal Centos 6.5, vncserver running, client able to connect with />/ perfect resolution.

mount options
by Fred Smith 19 Nov '14

19 Nov '14

Hi all! I've got a Venus DS3R Pro2 external drive unit with two drives set up as RAID-1, and the raid volume is formatted as ext4. it is listed in /etc/fstab as: UUID=f787c482-fb92-4ba7-87d6-cfeaef6b64c2 /mnt/backup ext4 defaults,users 0 2 if the external unit (which attaches via e-sata) is NOT powered on when the system boots, it hangs and drops to a maintenance prompt. I'd sure like to have it defer that particular mount and continue to boot. I've been perusing various mount man pages, but don't see any ext4 (or non-filesystem-specific) opotions to allow this. Can any of you offer helpful advice in this matter? Thanks!

Re: [CentOS] Centos7 Net install on HP A1710N fails
by david 19 Nov '14

19 Nov '14

Folks: This conversation was trying to get Centos 7 installed on a machine with a NIC that got de-supported in EL7. Following the advice to do as follows: - Install (via CD) the "minimal" ISO - add the RPM of kmod-forcedeth-0.64-1.el7.elrepo.x86_64.rpm from a USB stick, as obtained from ELPRO (install went without serious complaint) I'm at a loss of what to do next, namely - How do I tell Centos that there's a NIC, and how do I configure it? PS: There is no GUI, and the command line display is very tiny. Guidance would be appreciated. David

Hello, may be anyone familiar with some tool for viewing logs. I mean web-interface based, simple solution. I have developers, and I can't give them access to my Centos servers, but they want to see logs of Apache. I want to give them address like 172.17.17.21/logs and they will be able to watch logs of Apache in browser. I was looking a lot for something like this, but didn't find.

Centos 7 Nvidia openGL breaks vncserver
by Stan Cruise 18 Nov '14

18 Nov '14

Bare metal Centos 6.5, vncserver running, client able to connect with perfect resolution. Nvidia GT240, driver 331.49. Upgrade to Centos 7 with nouveau basic driver, all still works fine. Resolution poor on wire connected monitor, but perfect on vnc client session (1920x1080). Upgrade Nvidia driver via elrepo. 340.58; removed nouveau via 'Software' manager. Excellent wired monitor resolution. But >> Client vnc connect receives the dreaded 'oh no, something has .....' Backed out Nvidia 340.58, back to nouveau, client vnc works again. Also tried 304 driver (only other one in elrepo for el7) - same problem. Research seems to indicate that openGL does not play well with vnc. I cannot see any solutions posted as yet. So, what are my options? Maybe change out the video card for AMD? I cannot know if the Catalyst driver will work, but there is a much more active and extensive open driver community, which could work better than nouveau? And I noted the Linus 'salute' to Nvidia....... Good timing. Stan
