New linux install Leap 15.1 / KDE desktop
Older Dell machine Dimension 5100 w/ a Pentium 4 / 1.5 RAM (8MB dedicated to video card in BIOS)
Displaying Desktop folder vs widgets
My Desktop icons weren’t displaying. However the icon descriptive text shows, and when I click on a desktop icon to drag / relocate it the desktop icon shows. When I release it disappears again. Also the upper right menu shows as a rectangle w/ cut corners vs the hamburger menu.
When I decrease my screen resolution to: 1152 x 864 the desktop icons appear as well as the upper right menu
Setting resolution to 1280 x 1024 or 1600 x 1200 the icons disappear.
Now for the weirder part:
If I set my desktop resolution to: 1152 x 864 and restart the icons show as expected, I am also able to open the display manager and set the higher resolutions (1280 x 1024 or 1600 x 1200) the icons still show and I’m able to work normally.
however if I restart when set to either of the higher resolutions the the icons again disappear and won’t reappear until I set the resolution back to 1152 x 864
The monitor and card are clearly able to handle the resolution, I can’t figure out why the restart messes it all up unless I scale back; only after starting in the mode can i go to a higher res.
False. 8MB is the minimum reservation from system memory for video by the BIOS. The X driver will use as much additional system memory as it takes to support 1920x1200 @ 24 colors.
Possible you have problems with a too old video chip.
The northbridge chipsets that support 64 bit Pentium 4s are not too old. I have at least one running 15.1 with no apparent trouble, though Plasma I don’t run on it/them, which run KDE3 or TDE.
If disabling compositing doesn’t solve the problem, next I’d try logging out of Plasma, logging in on a vtty, and deleting the content of ~/.cache/. I’d also ensure all available updates are applied before logging into Plasma again. I’d also try reseating the RAM sticks, followed by an overnight run of memtest86. RAM can go bad. I’ve had probably a dozen RAM sticks from old Dells go bad.
Finally, that age Dimension is in a class of PCs subject to a high rate of electrolytic capacitor failures. It would do well to examine all motherboard caps for leakage and swelling. Only after I read this last reply several hours ago I tried to confirm my recollection of the video RAM issue on a Dell about 0-12 months older than a Dimension 5100, and it wouldn’t power up. I found 6 caps bad, replaced them, and was able to complete the verification using it, boot TW20191002, and upgrade successfully to TW20191122.
