Porteus Desktop Edition 3.0 rc1 bugs/feedback thread

checked few distros and this symlink does not exist anywhere. if really required by GE then must be shipped with this module.

[bdheeman]

Don't know, whether the following dangling symlinks have any effect on porteus scripts and, or applications, but they are invalid even in edition 2.1 as well.

Code: Select all

[guest@porteus:~]$ ls -l /mnt/live/porteus/
total 0
lrwxrwxrwx 1 root root 28 Jan  9 16:37 modules -> /mnt/isoloop/porteus/modules
lrwxrwxrwx 1 root root 29 Jan  9 16:37 optional -> /mnt/isoloop/porteus/optional

See/Check:

Code: Select all

[guest@porteus:~]$ cd /mnt/live/porteus/modules 
bash: cd: /mnt/live/porteus/modules: No such file or directory
[guest@porteus:~]$ cd /mnt/live/porteus/optional 
bash: cd: /mnt/live/porteus/optional: No such file or directory

Here is the fix:

Code: Select all

sudo ln -fs ../mnt/isoloop/porteus/modules /mnt/live/porteus/modules
sudo ln -fs ../mnt/isoloop/porteus/optional /mnt/live/porteus/optional

@bdheeman
fixed in linuxrc - thanks.

I've set the kde power manager to hibernate or other function on power button press.
But, pressing the button always results in shutdown.
Maybe KDE bug.

1. Google Earth(GE) problem
google-earth-stable_current_i386.deb/google-earth-stable_current_amd64.deb is gotten from
http://www.google.com/earth/download/ge/agree.html.
Then, it is converted to Porteus module
google-earth-7.1.2.2041-i386-1.xzm/google-earth-7.1.2.2041-x86_64-1.xzm.
Finally it is installed in system (activated).
When it is executed, it print out the message and exits.
#======= error message ======#
/opt/google/earth/free/googleearth: line 43: ./googleearth-bin: No such file or directory
#======================#

2. aboid this problem
(1) 32bit
# cd /lib
# ln -sf ld-2.17.so ld-lsb.so.3
(2) 64bit
# cd /lib64
# ln -sf ld-2.17.so ld-lsb-x86-64.so.3

3. other distros
If search with above error message,
you can get other distros reactions.

Especially, this site

This answer is simple and useful.

4. how to fix
"must be shipped with this module"
I think so, too.
I inserted the symbol linked entity into my
google-earth-7.1.2.2041-i386-1.xzm/google-earth-7.1.2.2041-x86_64-1.xzm.

@Slaxmax
disabled power off event in /etc/acpi/acpi_handler.sh for kde4 desktop only as we have power devil which handle buttons.

@neko
added this hack to my database so will be included in GE module in 3.0 repo.
thanks for sharing

On Porteus 3rc1 LXDE - chromium - converted package chromium-31.0.1650.67-x86_64-1alien.
(Havent tested the original chromium from porteus yet).
Chromium seems to be unable to apply rendering settings to its fonts. This gets solved by creating /root/.config/fontconfig/fonts.conf

Code: Select all

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <match target="font">
    <edit mode="assign" name="rgba">
      <const>rgb</const>
    </edit>
  </match>
  <match target="font">
    <edit mode="assign" name="hinting">
      <bool>true</bool>
    </edit>
  </match>
  <match target="font">
    <edit mode="assign" name="hintstyle">
      <const>hintslight</const>
    </edit>
  </match>
  <match target="font">
    <edit mode="assign" name="antialias">
      <bool>trget="font">

good news - all mplayer issues are gone (hopefully).

latest mplayer-vaapi does not work well with external ffmpeg-2.1 but there is better solution named: libvdpau-va-gl.
this library allows all systems with OpenGL (pretty much everything) or VA-API (Intel) acceleration to use VDPAU api for video playback.
VDAPU works well with latest mplayer but also flashplayer as described here:
http://www.webupd8.org/2013/09/adobe-fl ... dware.html

here is mplayer log from i3 system which utilizes VA-API over VDPAU (mind libva info: Trying to open /usr/lib64/dri/i965_drv_video.so):

hopefully will have all these goodies in rc2 of porteus-3.0 - testing in progress

@fanthom
this would indeed enable hw acceleration on lots of intel integrated gpus.
This will not work on AMD/Ati, when using proprietary drivers, since they dont include hw decoding AFAIK. Open-source gallium drivers (mesa) already include VDPAU interface, so they dont need the vdpau-va-gl wrapper, and most of them have hw decoding. On my friend's radeon hd 6670 gallium driver flash video acceleration (the rendering part) was accelerated out the box. I could not manage to enable the decoding part yet, but I was getting cpu usage at 10% while playing 720p vids from youtube (15% on 1080p). Still much better than software-only though.
I guess you have already checked

About my video crashes:
The same USB in another machine does not experiment video crashes. Therefore, this is not a bug. My machine seems to be now outdated....

However I did some research, substituting base modules from 3.0-rc1 with corresponding from 2.1. The issue stops when I fall back to the former 003-kde.xzm module. With the old module, after 10 minutes or so, the screen goes black, and when you move the cursor a "system blocked" window pops, you write your password and the system goes on.

With Porteus 3.0 in the other machine (the one that does not crash) when you move the mouse you see a flash and the system goes on, without showing the "system blocked" screen.

Maybe you eliminated the "system blocked" window in favor a still faster boot, or maybe it is a "hidden" bug...??

If you took it out (the system blocked window), i would like to restore it; otherwise I will have to stay at 2.1 or throw away this machine...

Regards

@dimx
yes - i'm aware of this
got accelerated flash on youtube on AMD HD 4550 and i3 Ironlake so this solution will be included for sure.

@wread

With Porteus 3.0 in the other machine (the one that does not crash) when you move the mouse you see a flash and the system goes on, without showing the "system blocked" screen.

please enable password locking in kde system settings -> display and monitor -> screen locker and check if that helps.
btw: this feature will be enabled by default in 3.0

bugs in archive manager eg. can't unpack .iso archives - "Setting attribute time::created not supported"

save session for deleted folders/files eg. 1. delete /home/guest/.mc 2. save session to module 3 reboot 4 .mc still exist

open current folder as root (pcmanfm) doesn't work if the first password character is space character.

Hello !
1st contact with V3 Razor
boot in text mode thru lilo

Code: Select all

Loading Razor . . . . .
Bios data ckeck successfull
Undefined video mode number :  303

this message does not appear with porteus 2.1, neither slackware 140 nor slackware 141
vesa mode problem ?

@tome

save session for deleted folders/files eg. 1. delete /home/guest/.mc 2. save session to module 3 reboot 4 .mc still exist

aufs whiteout files are not respected in upper branches (activated modules) so the only solution to this bug is to use 'changes=EXIT:' or 'changes-ro' cheatcodes.

@bour59
did you add 'vga=' cheatcode to lilo.conf? if yes then please remove it and check if booting is ok.
i have removed VESA framebuffer in favor of simple framebuffer as latter one seems to deal better with EFI and such.
