Make sure the xf86-video-intel rpm is installed and its provided intel DDX display driver in use to avoid the problem.
It is currently not installed, but I will try. How do I make sure the DDX display driver is in use? Do I check it with `lsmod`?
If there is a Xorg.0.log file, it over-amply reports driver in use. Inxi -G also reports loaded display driver.
I have installed xf86-video-intel and rebooted. I can now login into TDE and it is stable. However, there is still an issue with openGL. I can start an application to display 3D molecules (called VMD). Lines and cartoon representations work, but anything with spheres makes the screen flash and VMD crashes with "core dumped" (although I cannot find the "core" file).
There is no Xorg.0.log file. Can I or should I create one?
ls /etc/X11/xorg.conf.d
00-keyboard.conf 50-device.conf 50-monitor.conf 50-screen.conf
inxi -G

If xf86-video-intel causes problems and I want to remove it, can I simply remove the rpm?
Sure, but first: do the problems overlap, or are they an entirely different set?
The problem with openGL not working correctly (VMD) is the same as without xf86-video-intel. However, I can now login into TDE without seeing the flashing.
Does this old Inspiron only have an Intel GPU, or is it like its sister models in including also an NVidia GPU?
It only has the integrated Intel GPU GM965/GL960 (unless it is hidden somewhere, but BIOS only reports the Intel GPU.
What does inxi -GSaz report run from within any X session, e.g. IceWM if not LXDE or TDE?
inxi -GSaz

Which DM are you using? With TDE installed, I only ever use TDM, though I would expect it to be fine using LightDM or plain old XDM directly.
I am now using TDE. I use LXDE before installing TDE. But once TDE is installed, I do not login into any other DM.
Thanks!
