18.10 32-Bit: The 'Discover' software centre is Slow + Unstable.

[James Jeagar]

The Discover Software Centre on my Lubuntu 32-Bit test machine takes on average just over a minute to load completely, and tends to experience graphical issues when another window overlays it. Even once loaded, it is so slow that I would class it boarderline un-usable.
If anyone's interested, the system specifications for my test machine are as follows:
Toshiba Satelite A100-02M
-Hard disk 80 GB
-1,024 (512 + 512) MB, DDR2 RAM (667 MHz) - Upgraded to 2 GB.
-Intel Pentium Dual-Core T2080 (At 1.73 GHZ)
Running Lubuntu 18.10 Beta 32-Bit.

This is the first bug report that I've ever submitted for anything, so I hope I've done it properly.

Did a quick check on this :

This runs fine for me on my Dell GX620 Optiplex with 1 GB RAM- takes about 15 seconds to load and of course checks for updates as well.

Ok Leó thats odd, I'll have to try this on one of my other i386 machines to see if I can duplicate this. Lubuntu itself runs fine on my test machine, and it can run applications such as Firefox without problems as-well. I'll let you know how I get on with the other i386 machine.

What version is this? Usually `ubuntu-bug package` is the best way to file bugs as it will pull in information like this.

Just tested this again on today's Cosmic daily build 20181002 Lubuntu desktop i386 and no problem with the Discover software, again this was installed on a Dell Optiplex GX620 - 1 Gb RAM. The software loaded even faster than the Cosmic beta release Lubuntu desktop i386.

Tested, `discover` on my hp dx6120 (mini-tower, pentium 4 dual core 2.8ghz, 3gb, nvidia 7600gt, installed x86 system), it loaded in ~15 seconds, with updates check it was ~35 s (which includes the 15 secs appearance time) On that machine I couldn't fault overlaying windows (tried featherpad, qterminal & vlc overlapping discover). I didn't see any problems here.

Testing on my dell latitude d610 (pentium m, 1gb, intel i915) using a 'live' system however it was very different. the first screen appeared in ~13 seconds, but the number of updates available took ~90 seconds, and it took ~123secs for the full page to draw. Note: I'm using 20181001 build sorry; I haven't updated it.

On the 'live' running d610 though when I moved overlapping windows over discover, edging was left behind which it took a very noticeable time after I stopped moving before they disappeared.

Given the specs of my d610 though - I don't consider this a problem, there is just a short (yes it's noticeable) delay before the discover window is re-drawn. I'm not sure if this is what James saw or meant, but it was the only glitch I saw (which I did not see on my installed system with better cpu & more ram). -- two images will be attached (one of featherpad, one of qterminal 'waved' over discover & then dropped..)

Usage on the 'live' d610 system yes was painfully slow; and I could understand "borderline un-usable" being used to describe it. It crashed on me, and I noted the fan start & continue to run flat-out on the d610 (which I rarely notice), so discover appeared to make the system run pretty hard.

I however had no issues on my installed x86 system.

To the OP: several patches have been uploaded to Discover. We're up to the 6th Ubuntu patch on this version. That said, you should try again. If it still produces the same result, please run `apport-collect 1795632` on the machine you're experiencing the problem on to collect some more information about the system, plus logs, etc.
