I have F21 but it also did the same thing on F20. I use the java program thinkorswim from TDAmeritrade.
From the desktop computer, the program works correctly.
The laptop computer has a problem. The first screen displays correctly. The second screen that is for logging in has a lot of vertical graphics with black/white blocks. The screen is not readable but if you put the mouse at the correct place I am able to login.
After the applications is loaded, the rest of the application runs correctly.
This has only happened on laptops (2 laptops different brands, both F21). Both laptops work correctly otherwise.
When I remote login from my desktop to the laptop and run the application all screens display correctly on the desktop monitor.
I thought that I was missing a font on the laptop, but both laptop and desktop have the same fonts.
Has anyone seen similar problems.
Any ideas for what to check next?
Wild guess here: these laptops have Nvidia chipsets and are using the open-source Nouveau video driver...
your desktop(s) may or may not have nvidia and therefore may or may not be using Nouveau, but even if both are true, it's almost cfertainly a different Nvidia chipset, one with better support.
So, if my wild guess is true, you may wish to try installing the correct nvidia driver on one of the laptops to see if it helps. You can get Nvidia drivers for fedora from the elrepo repository.
Good luck!
Thanks for the quick reply.
The desktop is AMD CPU and video.
lshw shows that the laptop has Intel chips and the video is i915. lsmod lists video as i915 and the xorg-x11-drv-intel.i686 package is installed as well as the devel package. So, to me that indicates that the intel driver is the one being used.
If that conclusion is true, is the setup is as good as it gets and there is an application problem or is there another driver that I should try? If so how do I insure that this other driver loads in place of what is currently being used?
Sorry, I'm fresh out of ideas. I know little about Intel video. AFAIK, the drivers come with the kernel, which isn't to say it may not be buggy,...
Or maybe there's something else wrong, but right now I have no further ideas. Sorry!
I changed the minimum amount of memory for the program to use and that fixed the login screen but did not fix the next screen that show the progress of loading the program (not a big deal).
The line I changed is in the thinkorswim.vmoptions file and the line is: -Xms32m changed to: -Xms64m
