Could be related if say it's somehow a GTK issue. Is this only in the file picker or is this within the normal GIMP? I've used GIMP in 18.04 with no issues but I'm not a heavy user. That said, it's *probably* not related. > I apologize. I didn't meant impugn 18.10. I got the impression (from an > announcement) that it was "the fist step," early-adopter sort of thing. No. More like it's the first release of Lubuntu with LXQt. The previous cycle we actually made images available for testing, though none of them were ever released. And before that we were packaging things. It's certainly something we've put a lot of time in to get to the point where we feel like it is made for prime time.

The one problem with debugging tools is that you generally have to have them running and building up logs of activity while you try to reproduce the issue. Well, that's not normally a problem, but with one where you don't have a clear process to reproduce the issue, you may have to wait a long time, which might mean a huge log file. That said, some general advice on debugging is [available][1]. I apparently never read this document before because the bit about apport-retrace is not something I knew about. If your issue does indeed create a .crash file (I suspect it won't), that might be an easy way to figure it out.

I read halfway through that and will try to pay more attention to some things. For me this started with 18.04. But, I was running 17.04 (or 16.10). I skipped at least one version (maybe two or three. I don't remember. I know I had fallen out of support by the time I installed 18.04, software-update wasn't doing anything anymore.). I've always felt like it has something to do with mouse clicks not being handled well (clicking too fast). But, that could just be my imagination, looking for a simple reason. Filesystem is EXT4. Laptop is Toshiba C55-B5299 (inexpensive, no-frills. Celeron N2830 Processor, SATA drive; Intel HD graphics, shared memory.). I didn't think this is related because GIMP had a major upgrade. But, GIMP became very unstable for me (similar random freezing; kill it, start again). It's 2.10.8 right now. I don't know what it was back when I installed 18.04. But, it was the new, dark-themed 2.10. They changed it to use GEGL(?). So, I thought that instability was due to *that*. But, maybe it's related(?). 18.10 is already ready for primetime. Why wait? I apologize. I didn't meant impugn 18.10. I got the impression (from an announcement) that it was "the fist step," early-adopter sort of thing. Maybe in April I'll try it. At this point I think I'd like to find a way to detect what's happening with pcmanfm. I'll read the bug comments more thoroughly. It would be nice if there was some way to turn on debugging. I saw something about strace. Maybe that's what I need to use. It's not a hardship to have it crash randomly. I just wish I could view something and see what happened leading up to it. Maybe some pointers are in the bug report conversation. I'll spend more time studying that and post there.

Great stuff! I have upgraded a couple of old netbooks this way. They were usually not very fussy about RAM, as the Atom was quite a low-performance CPU and the chipset is similarly not high-end. E.g. no RAM interleaving or anything. > Did some testing of LibreOffice. Basically, it is a Java problem.

Some bits of LO and OpenOffice before it were written in Java. Not much -- e.g. some import/export filters. You could install a JVM -- the FOSS IcedTea runtime is in the Ubuntu repos. It won't take a lot of space and will enable a few more things to work. I use some Java text editors myself, for instance. I think if you do: sudo apt install icedtea-web ... that should pull in the current IcedTea JVM. Then you can check with: java -version ... at a shell prompt. > Thanks for the CEX tip. Looked at the website and it was very interesting. I've sold quite a lot of old kit to CEX over the years: many old mobile phones, routers, stuff like that. I took payment in vouchers and it enabled me to max out the RAM on a few computers, put a max-capacity MMC card in my smartphone, buy original copy of Mac OS X 10.6 Snow Leopard which I ran both on a real Mac mini and on a Hackintosh I built, and finally contributed towards an old iPad 2 for my mum, which she liked a lot. Later I got her an iPad 3 from them, and the iPad 2 went to a family friend who's still using it some years later. They're a very useful company. There are a few international branches, too. Disclaimer -- the 3 co-founders were personal friends of mine, and I worked there for all of a week in about 1996. But sadly they 2 co-owners are both dead now, and I have no connection at all with the company any more. The third, Charlie Brooker, who did all their original branding, advertising and so on, is now a famous TV writer (Black Mirror, etc.) and no longer associates with his old mates at all. :-( -- Liam Proven - Profile: https://about.me/liamproven Email: lpro...@cix.co.uk - Google Mail/Hangouts/Plus: lpro...@gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven UK: +44 7939-087884 - ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053 -- Lubuntu-users mailing list Lubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/lubuntu-users
