| pururu | i have horrible slowdowns like 20 seconds between switching tabs in browser (only few are opened), slow scrolling of text in terminal, etc. | 15:41 |
|---|---|---|
| persia | Which browser? Which environment? | 15:41 |
| pururu | this is acer aspire one netbook | 15:41 |
| pururu | default ubuntu-mobile | 15:41 |
| pururu | so, i think maybe xfce fit better for aspire one. cuz linpus (default os) uses xfce. but linpus have slowdowns too | 15:42 |
| pururu | anything like xubuntu-mobile exist? or i may try regular xubuntu | 15:43 |
| persia | Hrm. I'm not at all sure if you're running the default, as others have reported success with the same hardware. If you run gnome-system-monitor, does it show any resources fully used? | 15:43 |
| persia | I haven't heard of a xubuntu-mobile. The icons may be a bit small, but it ought to work. | 15:43 |
| pururu | actually gnome system monitor itself uses like 20-30 % of cpu, maybe even more | 15:44 |
| persia | Yeah. gnome-system-monitor isn't that lightweight, but it can help show if something else is also using too much. | 15:45 |
| persia | Also, whlie it uses 20-30% for a while after startup, it should calm down within 30-60 seconds. | 15:45 |
| persia | But the important questions are : aside from gnome-system-monitor, is something else using all the CPU, or are you low on memory? | 15:46 |
| pururu | what tweaks should be applied after ubuntu-mobile install? like described here https://help.ubuntu.com/community/AspireOne ? i have not applied all of them, only part | 15:46 |
| pururu | 300 of 490 memory used, and nothing else use cpu right now (browser is in background and it uses 0 %) | 15:47 |
| persia | I don't happen to have such a device, but I suspect most of the things that apply to Desktop should also apply to Mobile, except perhaps for visual adjustments. | 15:47 |
| pururu | switching tabs in pidgin is slow too (but not nearly as bad as in browser) | 15:48 |
| persia | 300 of 490 doesn't sound like a lot of pressure. Try (with gnome-system-monitor running), switching to the browser and switching tabs a couple times, then look back at gnome-system-monitor to see if there are CPU spikes at that time. | 15:48 |
| pururu | just moving mouse rise cpu use to 90% (1st core) | 15:49 |
| persia | OK. That's bad. Do you have desktop effects enabled? | 15:49 |
| pururu | no | 15:50 |
| pururu | maybe i should enable medium effects | 15:50 |
| pururu | cuz full effects make system slow too | 15:51 |
| persia | I'd recommend disabling effects entirely, as from what you describe, it sounds like you're processing the events on your CPU, rather than a GPU, which tends to be slow. | 15:51 |
| pururu | compiz should offload processing to GPU instead of CPU, but will it be better with this integrated mobile gpu? | 15:51 |
| pururu | .. | 15:52 |
| persia | Well, compiz offloads processing to the openGL engine, which may or may not be the GPU. | 15:52 |
| persia | Whether it works well with the integrated mobile GPU depends on how well that driver works. Which GPU? | 15:52 |
| pururu | Intel Corporation Mobile 945GME | 15:53 |
| pururu | i also use external monitor and antialiasing for text | 15:53 |
| persia | antialiasing shouldn't take much, and the external monitor shouldn't make too much difference. | 15:54 |
| pururu | good to hear | 15:54 |
| persia | I think your GPU should be supported, but I don't have one, so I can't promise anything. | 15:54 |
| persia | I'd recommend trying setting visual effects to "None" and seeing if that makes it stop being slow. If that doesn't help, just turn the effects back on. | 15:55 |
| persia | Not sure what else might be the issue, or why moving the mouse would take so much CPU. | 15:55 |
| pururu | its supported and DRI enabled, i even can play Quake with good performance. this CPU is probably as fast as Geforce 1st series, from glxgears scores | 15:55 |
| pururu | s/CPU/GPU | 15:56 |
| persia | Hrm. Dunno then. | 15:57 |
| pururu | ok i'll try playing with effects. do you know when netbook remix will be released? i hope they will include tweaks by default, like disable logging to SSD and such | 15:59 |
| pururu | i also not sure if this midbrowser uses SSD as cache like firefox do | 15:59 |
| pururu | no such option here | 16:00 |
| persia | I don't know about the release schedule for any remixes : you'd do best to ask the maintainers of the remix. | 16:01 |
| ian_brasil | pururu: i am on an aspire one a.t.m | 16:02 |
| persia | ian_brasil, Do you see the same slowdown? | 16:03 |
| ian_brasil | no | 16:03 |
| ian_brasil | well sometimes midbrowser freezes but not to the same extent as pururu reports | 16:04 |
| persia | Hrm. | 16:04 |
| ian_brasil | maybe it is the theme | 16:04 |
| ian_brasil | i was testing it on friday and it is pretty resource intensive | 16:05 |
| ian_brasil | pururu: try changing the theme to a metacity one to test this | 16:05 |
| ian_brasil | use gconf-editor for this and choose one of the themes in /usr/share/themes | 16:08 |
| ian_brasil | it uses NewHumanMobile as a default b.t.w | 16:08 |
| ian_brasil | desktop-gnome-interface-gtk_theme in gconf-editor and right click on the theme to edit it | 16:09 |
| pururu | oh... well... | 16:14 |
| pururu | i useing DarkRoom theme | 16:14 |
| pururu | (mm i should say "i'm were useing?" sorry for my English) | 16:15 |
| ian_brasil | what engine does this theme use? | 16:16 |
| pururu | its one of supplied with ubuntu-mobile themes | 16:16 |
| * ian_brasil looks for info about DarkRoom theme | 16:17 | |
| pururu | i see both metacity and compiz are running | 16:18 |
| pururu | i tried to switch to other themes, dont see any difference | 16:19 |
| ian_brasil | this uses the murrine theme engine which is very nice and all but is pretty heavy | 16:19 |
| pururu | (but not how you described, and just with appearence applet) | 16:19 |
| pururu | murrine? | 16:20 |
| ian_brasil | this is the engine which ' makes' the theme more or less | 16:21 |
| pururu | and human theme uses which engine? | 16:21 |
| ian_brasil | if you were to choose a theme based on Raleigh for example this would use much less resources | 16:21 |
| ian_brasil | the same murrine | 16:21 |
| pururu | interesting | 16:22 |
| ian_brasil | but also not look as nice obviously | 16:22 |
| pururu | maybe xfce or kde will be better? i also heard they included new type of acceleration for intel video in new Xorg, but it is disabled by default | 16:23 |
| persia | I've heard that the changes to KDE to work nicely on smaller screens won't land until 4.2, so you might want to delay that (although you may find a theme you like). | 16:24 |
| persia | I don't know the state of Xfce for high-DPI devices though. | 16:24 |
| pururu | mm this acceleration... probably DRI2 or something | 16:25 |

| ian_brasil | playing around with MID themes | 23:09 |
| ian_brasil | check out ubuntu golden | 23:09 |
| ian_brasil | http://ianlawrence.info/downloads/ubuntu-mid/ubuntu-mobile-theme.png | 23:09 |
| persia | That's fairly pleasing. That's kourou? | 23:10 |
| ian_brasil | what is kourou? | 23:10 |
| persia | The launcher for intrepid MID. | 23:10 |
| persia | Replaces mobile-basic-flash. | 23:10 |
| ian_brasil | erm, this is on hardy | 23:12 |
| ian_brasil | on the geode | 23:12 |
| persia | Oh. Pretty, but not directly importable :) | 23:14 |
| ian_brasil | like lots of things..pretty but useless! | 23:18 |
| persia | heh. | 23:19 |
| playya | do you have a central repo for the source? i want to have some parts on my n800 | 23:19 |
| persia | playya, archive.ubuntu.com | 23:19 |
| playya | i'm thinking of a git,bzr,svn,cvs, hg | 23:20 |
| persia | Then no. It's a collection of many pieces of software. The upstream software is stored in all of those and more. Debian packages most of the software, and Ubuntu the remainder, and patches are added where needed. The integrated collection becomes Ubuntu Mobile or Ubuntu MID. | 23:22 |
| playya | ok | 23:23 |
| playya | anyone tried to add openembedded recipes for some parts? | 23:23 |
| persia | I don't know of any explicit integration of that, but I could be mistaken. | 23:26 |
