Login loop with RHEL 7.4 after update
As I have mentioned in the title. I cannot login with the GUI after update. I am, however, able to log in after pressing ctrl-alt-f2 and going in that route.
Respectfully,
James

James, perhaps install vmware tools (manually)? I've seen oddball things when upgrades are done and vmware tools is not concurrently updated, occasionally. What form of system is this? vmware? Is this a server or workstateion? How long ago did you do the yum update, like in the last 2 days? (or a week ago from today, because Red Hat 7.5 was released this week) Is your update source Redhat directly, or do you have a Red Hat Satellite server?
Are you able to access the logs? Is the system Red Hat Server or Red Hat Workstation? Does the system use a graphics driver for a graphics card (maybe nvidia)?
When you reply, imagine you are reading this attempting to help someone else who has no idea of the specifics except what is provided and keep in mind what details the person helping you would require - and tailor your reply with sufficient details so someone cold to your situation will have sufficient information to provide viable help.

Hi James,
As I can see in the DELL Latitude E6520 Tech Specs, the notebook shipped with NVIDIA NVSTM 4200M Discrete Graphics with Optimus. This means that it has a hybrid graphics solution built in and hence the hint from RJ (R. Hinton) might lead to the root cause. This also would be the explanation why it works properly in a VM.
Please check whether the proprietary NVIDIA drivers are installed on the laptop. Uninstall all NVIDIA related software, reboot the system - reinstall the drivers and reboot again. Please check if there are settings related to the dedicated graphics adapter which would possibly have to be adjusted in the BIOS settings of the notebook.

Thanks for this information, James ! :) When I understand you correctly, the behavior of the VM was as expected after you've performed a fresh installation of RHEL 7.5 - is this correct ? And if it is, then try the same on the laptop. Hope it works there too, please report back the results. I wish you good luck !

Great James, I'm glad that you've got the system properly installed on the laptop too. But it's not that strange at all, a bunch of users are having problems when trying to upgrade their systems, simply because it very much depends of what is installed on top (which is individually different in each case). Exactly that is the reason why I generally recommend clean (fresh) installations. As I use to say, it takes less time than trying to fix possible issues (at least for not very experienced users).
Cheers :)

Hi James,
Not sure what you mean with locking the repos, but when you are only using the Red Hat repos, you won't have to expect many problems. When you install something from external sources, then you might have to care about dependency issues. Anyway, you can check if you find something in the knowledgebase by using the Knowledgebase filter. Before I lead you to something with wrong relevance, you'd better search yourself - and by the way, I would need to search there too. :)

Hello James,
This seems to me not an issue related to the upgrade to RHEL 7.y, but a generic issue with the nVidia graphics drivers not being provided to Red Hat. So you will encounter this issue with each kernel update. I have a Lenovo Thinkstation E30 where I added a nVidia Geforce 730 graphics card running RHEL 6.9. After each kernel update I need to switch to runlevel 3, run the NVIDIA-Linux-x86_64....run program and which back to runlevel 5.

Hi Jan Gerrit,
I do not know whether James has the proprietary NVIDIA drivers installed, but he had the same issue also in his VM and there these drivers won't be the culprit. When he uses the drivers from RPM Fusion, he doesn't have to reinstall them (akmod version) after a kernel update, this is mainly valid for the NVIDIA drivers (run file) installation method. When he uses the open source drivers - it also should work without problems ... meant to be just an information ... :)

Hi Jan Gerrit,
Yes I know, it sounds a bit strange, but with "update" he meant a fresh install of RHEL 7.5 in the VM.
Quote (question) Christian : "When I understand you correctly, the behavior of the VM was as expected after you've performed a fresh installation of RHEL 7.5 - is this correct ?"
Quote (answer) James : "Yes, it was. Will try the same on Monday with the laptop!"
Anyway, most important is that RHEL 7.5 runs properly on both machines now - on the physical and on the virtual one. :)

Christian
