Screen refresh/flickers on cursor movement/slow refresh #315

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Boot an IBM Thinkpad 240 with android-x86-2.2-generic
2. Move the cursor or do just about anything that modifies the screen
3.

What is the expected output?
Smooth cursor movement, unnoticeable refreshes, 
What do you see instead?
Lots of screen refreshes and jerky cursor movement

What version of the product are you using? On what operating system?
2.2-generic

The IBM Thinkpad 240 is a low spec machine. 300MHz Celeron processor. 192MB 
memory. However, this spec is adequate to run Lubuntu 10.4 without problems and 
there are no graphics problems under XWindowa using the X.Org driver for 
Neomagic chipsets. While I have not tried using the machine with the neofb 
framebuffer device configured there are (old) reports of success of using X 
with the framebuffer.

I have tried various boot parameters as recommended without success, i.e. 
nomodeset, xforcevesa, vga=788 

Please provide any additional information below.
The Android installation was done on another machine and the disk moved to the 
240.

Does Android use framebuffers differently than regular Linux apps do?
