I upgraded my Samsung n135 netbook to Ubuntu 11.10 today and encountered some … issues:
The upgrade process didn’t disable the powersave schedule, which suspended my computer and the ongoing upgrade
After the upgrade (which took hours to complete), the screen flicker problem I already knew proved to have become worse, to the extend it rendered my system unusable. A blunt “rmmod samsung_laptop” stopped the flicker (actually powersaving trying to change the screen brightness).
Just a couple of small updates on previous stories to keep you posted really.
We’ll start of with Ubuntu Natty Narwhal; beta 2 has been released earlier today. I’ve downloaded a lot of updated packages over the last few days, so I guess I’m on the second beta as well. The Unity launcher now comes out of hiding perfectly and it scrolls down automatically to show items at the bottom as well. There also was a bug with the menu-items of some applications (e.g. Firefox 4) disappearing which seems fixed. Hope they can get the launcher to behave with Java apps (e.g. my favorite mindmapping application) soon.
On another note: Lookout, the Android app that allows you to locate your handset and -if you have the paying version- remotely wipe it, seems to be getting some serious competition from …. Google. Enterprises who have Google Apps for Business can now locate, encrypt and wipe their Android devices. Especially the encryption is important news, but it really should be available and configurable in the Android OS itself
supercharges your self‑hosted WordPress site with the awesome cloud power of WordPress.com
Jetpack actually is a “super-plugin” that offers functionality from Stats, Sharedaddy, After the deadline and other previously separately available Automattic plugins. The Jetpack WordPress.com stats module does still include the Quantcast “spyware”, doesn’t disclose this feature and doesn’t provide functionality that warrants Quantcast inclusion (in spite of Matt Mullenweg claiming “We’ve been using Quantcast to get some additional information on uniques that it’s hard for us to calculate”). But there is (some) good news in the Jetpack Stats source code though, because on line 145 it reads:
‘do_not_track’ => true, // @todo
This could mean that blog-owners will one day be able to opt out of 3rd party tracking or it might be that Stats will take e.g. Firefox DNT-header into account for your blog’s visitors. Having both would off course be what I will be rooting for!
Compiz replacing Mutter also seems to have a (very) positive impact on windowing performance.
But this is beta 1, there are bound to be some bugs and especially the launcher isn’t perfect yet;
sometimes only half of Unity launcher appears when it comes out of hiding.
I couldn’t make the it scroll down to see the icons at the bottom.
And non Unity launcher-related: the screen sometimes flickers while the brightness seem to be auto-adjusting (which shouldn’t happen as there’s no light sensor in my netbook) UPDATE: this got even worse after upgrading to Ubuntu 11.10, but there is a solution
Anyway, beta 2 is expected April 14th and the final release should hit the web on the 28th. Looking forward to a Ubuntu that’s perfect for my teeny weeny netbook. I’m curious to see how Gnome3”s Shell will do in comparison!
Aangezien ook dit jaar blijkbaar enkel de brave kindjes speelgoed van Sinterklaas kregen, heb ik mezelf afgelopen weekend dan maar een cadeautje gekocht; een n135 netbook van Samsung. Een beetje tegen de tablet-stroom in, ik weet het, maar ik ben zo tekst-georiënteerd. Geef mij een toetsenbord en ge hoort mij niet meer. En dan is er de kwestie van de prijs natuurlijk. Een 5 maand oud netbookje voor nog geen 200 Euro (met dank aan koopjeszoeker.be), daar hebt ge niet veel tablet voor, toch?
Soit, zondagnamiddag thuisgekomen pakte ik blij verrast mijn cadeautje uit om dan 5 minuten schaapachtig naar Windows 7 Starter te kijken. 2 minuten hadden kunnen volstaan, maar Windows 7 op een netbook, echt snel is dat toch niet. Maar zo wist ik dat ik Ubuntu 10.10 Netbook Edition met een gerust hart kon installeren, die Windows zou ik niet missen. Over die installatie valt weinig spannends te vertellen, behalve misschien dat ik een beetje heb getwijfeld over de partitionering van de harde schijf. Uiteindelijk heb ik sda1 en sda2 laten staan, dat lijken de recovery-partities van Samsung (met oa de Windows 7 installatie-bestanden). Voor de rest: smooth sailing!
En op die manier zit ik nu op de trein met m’n netbookje (6 uur autonomie, geen schrik van vertragingen); stukje bloggen, m’n presentatie over website-performantie bijwerken, een eerste versie van een nieuwe WordPress-plugin (DoNotTrack) tweaken … Straks nog een mailtje naar Sinterklaas, beloven dat ik braaf zal zijn en of ik in Juli dan een HTC Desire Z (met toetsenbord) krijg.
This weekend I had to resort to Joikuspot (software that turns your 3G-cellphone into a wireless gateway to the internet) for my web-needs. Because I encountered a few problems setting up a connection from my Ubuntu laptop, here’s a quick recap for documentations sake. The rather fundamental issue was that I couldn’t get my computer (a Dell D620 running Ubuntu 8.04 with the iwl3945 driver) to join the ad-hoc wifi-network which Joikuspot (on a Nokia e61i) created. As connecting from my wife’s Windows XP laptop did work, I googled around a bit and it turned out I had to specifically set the channel used by Joikuspot to 1 or 6 instead of “automatic” or 11. Although NetworkManager still seemed confused, this did allow me to connect from the command line (disabling wireless networking in NM first and then using iwconfig and dhclient). But why joining an ad-hoc wifi-network on channel 11 doesn’t work in Ubuntu, that I still don’t know. Once connected to the wireless network, I found out that Joikuspot Light requires your browser to auto-detect a proxy. The proxy in Joikuspot seems to be used to limit the functionality of the free version and gently push you towards the non-free Premium product. As my normal web-connection came back soon after I figured this out, I didn’t bother to test if I could tunnel my way out of those limitations. But crippled or not, Joikuspot is great to have around when your broadband connection is down.
Let’s start with the results for the browsers on my Windows XP SP2 installation, ordered from slowest to fastest. Each test was executed 2 times, clicking on the results will teleport you to the detailed results where you can paste the URL’s of another test to compare.
The MSIE7-results are probably not entirely representative, as I use Tredosoft’s standalone IE7. This is a bit of a hack to have IE7 on my otherwise MSIE6-based system. Moreover my corporate Windows-installation is infested with crapware, notably McAfee OAS and Zonealarm seem to be slowing things down enormously. The codinghorror-tests indeed show significantly better results for this browser, although IE does have serious issues with string concatenation, which should be fixed in IE8.
On the same hardware, but booting in Ubuntu 8.04 (Linux) form my external USB HD (a.k.a. my ‘disktop‘), I got the following results:
konqueror 4: not tested yet, results will follow later today can’t get test to completely run, any KDE-user want to give this a try?
Firefox 3 RC1 seems slightly slower then b5, but maybe the Ubuntu-b5-version is compiled with optimizations? Firefox is also faster on Ubuntu, but the anti-virus-bloat is probably messing with our heads here (although Opera is slower on Linux, go figure).
