ATI Open vs. Closed-Source AIGLX Performance

Filed under
Software

For those that may have missed it, the ATI/AMD fglrx 8.42 display driver that was released last month had introduced AIGLX support. The open-source "Radeon" driver for ATI graphics cards going up to the R400 generation has supported AIGLX for quite some time, but the ATI binary display driver hadn't until last month. However, one of the complaints about the fglrx implementation of AIGLX is that in the 8.42.3 driver, some are encountering slow performance in Compiz / Compiz Fusion. We have taken an ATI Radeon X800XL 256MB PCI-E graphics card, which is supported by both the Radeon and fglrx drivers, and have compared their Compiz performance in a few different scenarios.

Compiz 0.6.0 was used with Ubuntu 7.10 "Gutsy Gibbon" and the Linux 2.6.22 kernel with X server 1.3. The hardware included a PCI Express x16 based ATI Radeon X800XL with 256MB of video memory, an Intel Pentium D 820 (2.80GHz dual-core) processor, 2GB of DDR3-1333 memory, and an ASUS P5E3 Deluxe (Intel X38 Chipset) motherboard. While these tests are not scientific, we had used the Compiz Benchmark plug-in to measure the frame-rate when different Compiz effects were occurring on the desktop. These test scenarios had included the fire effect, water effect, window hovering, and then just idling within the GNOME 2.20 desktop. Testing was done with the stock "Radeon" driver that ships with Ubuntu 7.10 and with the fglrx 8.42.3 binary driver.

KDE: Simple by Default, Powerful When Needed

KDE (back when it was still the name of the desktop environment) and our applications historically stood for powerful features and great flexibility and customizeability. This is what our users love about our software, this is why they choose Plasma and KDE software instead of one of the other Free desktop offerings. And it is also something they would fight tooth and nail for if we wanted to take it away (as many a KDE maintainer who dared to remove a feature he thought was unnecessary can tell). Read more

BitTorrent Bleep alpha released for Android

As an alpha it still has some issues “As with any Alpha, there are some known issues and bugs to work out. Android users will need to set the app to “Wi-Fi Only” unless you have an unlimited data plan; this is only for the time being while we iron out and issue related to battery and data-plan. And while you can move a username from desktop to mobile, Bleep does not yet support moving an existing account from Android to the desktop. And while you can receive messages on multiple devices; messages sent will not be seen across all devices. As with our previous release, communications happen only when all parties are online – you cannot send offline photos or group chats asynchronously.” Read more

During Akademy 2014

This year there were lot of fast track (10 minutes) talks on different areas around KDE. All of them were quite interesting, some of them are: Bruno Coudoin talked about how and why GCompris moved to QtQuick with the support of KDE. What all challenges project faced while moving from GTK to Qt. Daniel Vrátil talked about his one year journey with Akonadi Martin Gräßlin gave an overview of current state of Kwin in adding Wayland support and future plans. Kevin Ottens talked about KDE craftsmen where analysis was on the way we handle our software production, how can we make our software even better. Kai Uwe Broulik talked about current status of Qt port on Android and iOS. Currently, 3 iOS apps in Apple store and 8 Android apps in Google play since December 2013. Read more
