It's not wrong. We need replace initial non-working with USB-flash ISO for more older (but identical) without Beta words in menu.

===Incorrect screen resolution after boot===
 +
If you monitor supports high resolution but a lower one is chosen during the boot, use the following workaround:
  
You may still download initial ISO (not work from USB-flash drive) from this URL:
+
1. Install '''lxrandr'''
  
* http://cdn.2safe.com/1518011033537/ROSA.2012.Desktop.Beta1.i586.iso
+
2. Launch it from a command line AS A USER and set necessary resolution from the list appeared

===Run ROSA in basic mode doesn't launch the live mode===
+
3. Press SAVE to create a config file that will be automatically used in future
There is a mistake in the launching command for this item. Just don't use it for now.
+
  
==Hardware issues==
+
===When using proprietary NVIDIA or AMD/ATI drivers, artifacts can appear on the screen during the boot===
===After installation system fails to boot from time to time===
+
For some video cards (especially embedded in AMD ATI 6300 chipsets) boot process can fail. To solve this problem, edit the following line in the /etc/default/grub file (with root privileges):
+
  
GRUB_CMDLINE_LINUX_DEFAULT='splash=silent logo.nologo'
+
If you see artifacts on your display, press Ctrl+Alt+Backspace to restart X-Server
  
and add nomodeset option:
+
===I have hybrid ATI/Intel graphics and I cannot boot using ATI card===
 +
Unfortunately, the full-featured support of this combination is announced but not implemented correctly (yet) in X-Server 13. Use Intel graphics card by disabling AMD/ATI one in BIOS or add "xserver=intel" by editing the following line in the '''/etc/default/grub''' file (with root privileges):
  
  GRUB_CMDLINE_LINUX_DEFAULT='splash=silent logo.nologo nomodeset'
+
  GRUB_CMDLINE_LINUX_DEFAULT='splash=silent logo.nologo xserver=intel"
  
Then update grub2 with the following command:
+
Than run '''update-grub2''' command.
  
  grub2-mkconfig -o /boot/grub2/grub.cfg
+
Also you may use proprietary ATI/AMD card drivers. For this run
 +
 
 +
  XFdrake
 +
 
 +
Setup proprietary card, than DON'T REBOOT SYSTEM and run (from root)
 +
 
 +
amdconfig --initial -f
 +
 
 +
===High CPU usage for some machines in KDE4===
 +
 
 +
In some machines KDE was get high CPU usage. This error related to KDE4 powermanager problem. For avoid this editing the following line in the '''/etc/default/grub''' file (with root privileges):
 +
 
 +
GRUB_CMDLINE_LINUX_DEFAULT='splash=silent logo.nologo acpi=off"
 +
 
 +
Than run '''update-grub2''' command.
 +
 
 +
===Backlight/Brightness workaround for laptop Packard Bell TE11HC-B8302G50Mnks===
 +
 
 +
The FN-F11 and FN-F12 combinations doesn't work to adjust brightness/backlight of screen.
 +
When you push this combinations nothing happens.
 +
 
 +
Solution:
 +
To have a functional brightness adjustment you need to put acpi_osi=Linux acpi_backlight=vendor on the grub line with mcc.
 +
After a reboot all is ok, you can set brightness up or down with button combo.
 +
 
 +
===Workaround for keyboard's additionnal €, $ and lens key===
 +
 
 +
Need to add this at the end of /etc/rc.d/rc.local (for the moment):
 +
 
 +
setkeycodes e01a 217  # Touche loupe
 +
setkeycodes e034 219  # Touche $
 +
setkeycodes e033 221  # Touche €
 +
xmodmap -e 'keycode 229 = EuroSign'
 +
xmodmap -e 'keycode 227 = dollar'
 +
 
 +
===Start in recovery mode===
 +
Start in recovery mode.
 +
Mode "recovery" isn't present by default in ROSA Grub. If you find yourself stuck for one reason or another you can still force a recovery boot by following this procedure:
 +
 
 +
1. Boot to the standard Grub2 menu and stay with the first entry
 +
 
 +
2. Type "E" for edit
 +
 
 +
3. Locate the line "init =/lib/systemd/systemd" and move the cursor at the end
 +
 
 +
4. Insert a space then type => "failsafe" as shown the example
 +
 
 +
[[File:Grub2-Rosa-004.jpg]]
 +
 
 +
5. Then, without doing anything else, press the F10 key.
 +
 
 +
You are in console as root to make corrections
 +
====Add "recovery mode" in grub====
 +
It is possible to always have "recovery mode" entries in the grub bootloader
 +
 
 +
1. Go to the KDE Control Center (systemsettings)
 +
 
 +
2. Go to "System Administration" section, select "Startup and Shutdown" and check the option to generate recovery entries.
 +
 
 +
=== Failed to start ROSA on DELL D610 and similar models ===
 +
Symptoms: Boot menu appears correctly, you can select Install entry, then you have the dracut screenloader.... And this is it. End of story. Nothing happens after... except a black screen.
 +
 
 +
Solution: Disable the touchpad in BIOS and use a external mouse. You can enable the touchpad once the system is install.
 +
 
 +
=== ATI Radeon HDMI audio issues ===
 +
To make HDMI sound functional in a system with an ATI HDMI sound adaptor, one needs to do this:
 +
 
 +
1. System up to date.
 +
 
 +
2. Go to the KDE Control Center (systemsettings)
 +
 
 +
3. Go to "System Administration" section, select "Startup and Shutdown" and select "GRUB2 Bootloader" section.
 +
 
 +
4. Go the advanced tab then add "radeon.audio=1" to the "All entries" field and Apply.
 +
 
 +

replace it with:

===A message about missing update sources is displayed===

try use this workaraund.
Update repositories and possibility to update using GUI tools will be available only after release. Currently you can update to the latest versions of packages from console using the following command (under root):
+
  
urpmi --auto-update
+
Run
  
===A lot of gtk/gtk2/gtk3 errors===
+
/usr/lib/iptables.init start
There can be errors with gtk applications, or such aplications may not work at all. We will be glad to know about such cases since since update of gtk stack is not completed yet.
+
  
===DEs except KDE4 don't work===
+
or for 64 bit
Gnome3 and LXDE are supported by community and may not work properly at the moment. Maybe the situation will be improved in RC
+
  
===New graphical themes are not applied===
+
/usr/lib64/iptables.init start
Since gtk3 theme for ROSA is not ready yet, there can be some differences in appearance of different applications.
+
  
 +
and then restart system.
  
 +
Now firewall will work.

Drakfirewall/Shorewall not work

If you has non-worked drakfirewall (or simple shorewall) and test shorewall service get you error like this

try use this workaraund.

Run

/usr/lib/iptables.init start

or for 64 bit

/usr/lib64/iptables.init start

and then restart system.

Now firewall will work.
