mesa window rendering issue

[mahmood]

I used to run abaqus 2016 on centos 6 without any problem. However, the same version on centos 7 has some rendering issues. The command is ABQLauncher cae -mesa. Even I dropped -mesa, but the result can be seen in the attachment. As you can see other windows and menus are fine.

The following mesa packages are installed

Anybody has an idea?

You could try updating from the CR repository to what will shortly become 7.6 once it's finally released. All the mesa packages that you list that have version number 17 are now 18.

Thank you. Is there any beta repository for that?

Meanwhile I want to try XCFE or KDE instead of GNOME for that particular user. Currently, I have installed XCFE with the following command

Code: Select all

yum groupinstall xfce

I want to know where should I edit so that the logged in user sees XFCE instead of GNOME? I see some old post in viewtopic.php?t=11123
Is that still valid for 7.5?

I see this topic https://superuser.com/a/1355861/154815 but there is no such file on my system. Should I create that? Is that a system wide method?

To switch desktops you need to hit the little twisty on the login screen under where it prompts for the username, prior to logging on. The CR repo is already populated with packages, all you need to do is enable it and update - e.g.

yum --disablerepo=\* --enablerepo=cr update

You may also need to specify --noplugins if you have configured yum-plugin-priorities to give a higher priority to the base and updates repos (or assign the same or higher priority to CR first).

I think it is better to try other desktops and see if they can help me.
The user connects through vnc. So, he first turns on the server like vncserver -geometry 1300x800 :4 and then connects with IP:5904 and see the following login page. There is no little "setting" like icon which you mentioned.
