OR scrolling up. The install was fresh, on a Dell Vostro 1500 Intel dual core(32 bit) which ran opensuse 13.1 perfectly. I noticed the problem started last night after software upgrades listed below. The problem also leave behind a fragmented window until you move the page up/down. I tried switching the kernel back, and it made no difference. Happens with all windows, including Firefox. One strange thing, the problem does not happen when I go into Firefox about:config and scroll down. As soon as I go back to any webpage, it happens.
All installed packages from opensuse & Packman repos.
kde plasma - 5.11.3
kde framework - 5.40.0
qt - 5.92
kernel - 4.14.3-1pae
Also have a problem of crashing once in a while, and keyboard short cuts don’t work…etc…cut, paste , copy
according to these sites https://www.pcmag.com/article2/0,2817,2218214,00.asp https://ark.intel.com/products/29760/Intel-Core2-Duo-Processor-T7300-4M-Cache-2_00-GHz-800-MHz-FSB
your cpu is 64bit the down side is low amount of ram your laptop has (only 2 GiB)
according to pcmag their Dell Vostro 1500 came with nVidia GeForce 8400M
plasma 5 does not work well with the noveau driver you need the nvidia propitiatory driver
the 8400 uses the G03 driver which needs patching before installing on TW and it needs to be installed the hard way, as I haven’t done that I’ll leave it for someone more experienced to comment about it
for a system with so little RAM you need the propitiatory driver so you can offload a lot of processing to the GPU as pcmag and intel say your cpu is 64 bit I would recommend installing LEAP and getting the G03 nvidia driver for LEAP
you could also go for a lighter desktop I can recommend lxqt with openbox it’s not as flashy as plasma 5 but it will run smoother then plasma 5 on a system with 2 G or RAM and no hardware acceleration
This computer worked perfectly with opensuse 13.1. Also, when installing packages, I received a warning about a package that was known to cause system instability and crashing. I forgot what it was. Any idea? Because it was installed. I’ll remove it.
To be honest, I thought the Intel Core 2 Duo CPU for my Vostro 1500 was a 32 bit, which is why I installed the 32 bit. The Mesa-dri-nouveau package was the one I saw! Glad you said that. Let me try removing the package.
