problem with graphical interface

[muppy]

Good morning,
i'm nw to CentOs. At a first, i installed centos without any graphical interface. At a second time, i add graphical interface using the command
yum -y groups install "GNOME Desktop"
I now connect to the centos using a windows pc and putty+xming. After logging in, i type the command startx, but i get the following error

(==) Log file: "/var/log/Xorg.0.log", Time: Wed Sep 7 15:29:05 2016
(==) Using config directory: "/etc/X11/xorg.conf.d"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
pci id for fd 12: 102b:0534, driver (null)
EGL_MESA_drm_image required.
gnome-session-is-accelerated: llvmpipe detected.

As a result, graphical interface does not start. Any help to solve this problem ?
Best regards,
Andrea

Did you update after installing the GNOME Desktop? Did you install any third party drivers? Starting X (startx) manually should not be required. Just change the default systemd target

Code: Select all

systemctl set-default graphical.target

as root.

You cannot run startx from an ssh session, you must have a local console.

Ok, if i can not run starx from SSH, how can i add to centos a graphical interface and connect to this graphical interface remotely ?

Thanks

You'll need to use something like vnc or freenx.

would also teamviewer work ?

Thanks!
