I'm trying to use krita, (a painting application) but I'm having problems with it. I asked and searched, and it may be because the video driver is broken. So I'm wondering if there is a way to test the driver or update it individually, because everything works fine, it is just this application in particular. So far I got that intel drivers come with the kernel. Updating the whole kernel is the only way?

Here I left my driver info:

sudo lspci -nnk | grep -A3 VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)
        Subsystem: Hewlett-Packard Company Device [103c:30f7]
        Kernel driver in use: i915
        Kernel modules: i915
If I got it all mixed up, please have me patience, I'm new to this.
Thanks for reading. I'd appreciate any clarification.
