HDMI/VGA display detection

with one comment

Does anybody knows how to detect second display before Xorg or GDM loads? I’m always moving between home with second display (through hdmi) and another places with just my laptop screen 🙂

Why am I asking. Ok I can enable second display in Catalyst Control Center (CCC), but for applying changes I need to re-login. Next I need to enable Xinerama and re-login again. Now I have two working displays. Next I move somewhere without additional display, boot my laptop. It boots to login screen with wrong resolution (1280), I login, disable Xinerama, re-login, disable second display, change resolution back (without re-login). That’s too m uch moves to enable/disable second display. Oh I forgot to mention, it’s all about FGLRX of course. XrandR does not work with Xinerama enabled. I guess radeonhd should work ok, but I need performance.

Here is what I want. Just before login screen appears system should check if second display connected and load appropriate configuration for Xorg.

I know how to detect it after GDM loads Xorg, and I’ll post a solution soon when I test it. But I want a better way out.

Stay tuned.

New sony-laptop brightness control

with 44 comments

I’m thinking on updating this module with another brightness control which does not require DSDT patching.

It’s based on changing hardware registers on Ati card and work with radeonhd and fglrx drivers only. Worth it or not, what do you think guys?

It’s possibly would not work with power manager, only with fn keys and maybe without onscreen osd 🙂

If someone have laptop with fullhd screen, I would like to test this method with you, because you have another Ati card.

HDMI Works

with 22 comments

Tested HDMI output with plasma today. Works great, but Xorg needs to be restarted every time you want to connect a tv with fglrx.

UPD: Sound trough HDMI works only with fglrx or radeonhd driver.

Fglrx and PowerPlay

with 14 comments

I guess I’ve found why glxgears have so low fps with fglrx. It’s because of PowerPlay.

Even when laptop is on AC power, it show me only 400+ and fps goes higher when I scroll something in Firefox =) (that’s strange)

I have turned off PowerPlay in Catalist Control Center and it gave me 4k-5k fps.

Another what I’ve found is that cpu is much cooler with fglrx (even with PowerPlay turned off) then with radeonhd. Seems radeonhd eats more cpu. I was thinking it is because of cpufreqd, but was wrong.

Moved to Intrepid

with 5 comments

So I have updates to 8.10 completly.

Wifi works out of box.

Fglrx installed from Hardware Drivers works. Compiz works with fglrx (but there is still a scrolling lag in Firefox, so I’m not using Combiz because of that).

Audio works (using ALSA everywhere). When you plugin headphones laptop speakers does not turn off.

I can’t make work a radeonhd driver from repos, I guess I need to compile a new one.

Edu mentioned that we can enable brightness control with radeonhd, I’m going to do that after I make radeonhd works. (checked, xbacklight does not work)

Bluetooth works (my switcher not).

My wireless mouse works (well it works anywhere 🙂

Undervolting stops working, need update for new kernel. My CPU is cool enough I guess (41C right now).UPD

I have moved back to powernowd from cpufreqd (cpu is hotter with it, maybe someone saw that too?)

I thought there will be new OpenOffice 3, but there is only 2.4, and old Firefox (3.0.3)

P.S. Tried to update another laptop today, but repos speed is too low, maybe it’s overloaded, seems people update their Ubuntu today too =)

P.P.S. I’ll update post if remember something bad =)

UPD: xbacklight does not work.

Video: Ati Mobility Radeon HD 3470

with 6 comments

I have Mobility Radeon HD 3470 on my FW11ER laptop.

I’m on Ubuntu Intrepid alpha 4 now and while there is new X server, the official drivers from Ati desn’t work (this bug is already reported).

I have luck with installing radeonhd video driver, but it still have no 3D acceleration support with 2D at the same time, but for my work it’s just fine. Anyway it’s better than “ati” driver used by default in Intrepid. You need to compile version from git repository because 1.2.1 is not working, there is a bug with display detection.

You need this packages installed to be able compile it: build-essential, autoconf, autogen, automake, automake1.7, autotools-dev, xorg-dev, x11proto-dri2-dev, x11proto-xf86dri-dev, xserver-xorg-dev, mesa-common-dev and maybe some more =)

There is a guide about compilling and installation of radeonhd on x.org wiki.

Once you checkout git repository, the guide says that you need to configure before compiling with this command: ./autogen.sh, but for Ubuntu you need do it like this:
./autogen.sh --prefix /usr --libdir /usr/lib
sudo make install

Thats all at the moment, video is working.

UPD: The list of developer packaged needed before compiling:
