Public bug reported:
Hello,
Just upgraded to Lubuntu 32-bit 14.04 from 13.10 on April 18th, 2014.
- System is a P4, 2.8Ghz, 3GB RAM,
- NVidia GeForce 5700LE AGP graphics card with proprietary legacy video drivers
manually installed from Nvidia site (VERSION 173.14.39, RELEASE: 2013.12.6 -
the latest possible version available for my graphics card).
- Motherboard is ASUS P4P800-E upgraded to the latest BIOS available.
Prior to the upgrade, the arcade emulator MAME, the Commodore 64
emulator VICE, and the Commodore Amiga emulator FS-UAE worked
fantastically in full screen scaled mode. No delay, smooth performance.
Reasonably low CPU usage for a processor of this vintage.
After the upgrade to 14.04, all full screen modes (1080x1920) in these
emulators bring the system to a crawl. Sound from the emulator is broken
up, framerates are terrible (like two frames a second), CPU usage is
near or past 100%. I suspect other OpenGL software using full-screen
scaling would also be affected, but these are the only three pieces of
software I have to test with.
I've found that in MAME and VICE, I can work-around this problem but
shutting off "hardware scaling". Essentially (I think), this takes my
graphics card out of the loop and does the scaling in software/CPU.
Scaling down the resolution of the emulation helps too. Frame-rates are
better, CPU usage is lower by a factor of 30 to 40%. However, because of
these "work around measure" the overall user experience of the emulators
is severely impeded.
I also ran glxgears as a test and resized the window from its original
small size, a little bigger every five seconds, until it was the full
height of the screen (1080 lines) and got the following results:
Code:
brent@Brent-Lubuntu:~$ glxgears
552 frames in 5.0 seconds = 110.342 FPS
593 frames in 5.0 seconds = 118.471 FPS
416 frames in 5.0 seconds = 83.071 FPS
315 frames in 5.0 seconds = 62.810 FPS
287 frames in 5.0 seconds = 57.252 FPS
197 frames in 5.0 seconds = 39.354 FPS
165 frames in 5.0 seconds = 32.789 FPS
130 frames in 5.0 seconds = 25.937 FPS
124 frames in 5.0 seconds = 24.781 FPS
117 frames in 5.0 seconds = 23.274 FPS
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
after 25689 requests (25666 known processed) with 0 events remaining.
I had originally switched to the Nvidia proprietary driver from Nouveau
because of slight artifacts and stuttering in the latter. The
proprietary driver mentioned above worked like a dream in 13.10.
MP4 videos played in VLC VideoLAN player still play well, with low CPU
usage.
Based on my limited knowledge, this seems to be a problem with the
graphics card full-screen scaling to 1080x1920 (desktop & monitor
screenmode) under 14.04. Might have to do something with OpenGL?
The system works very well, other than when these emulators try to go
into full screen mode.
My Xorg.0.log file shows the following (notice the error lines):

One way of duplicating this bug (if you are using an NVidia legacy
driver and graphics card):
1. Install the latest version of the VICE emulator
2. from terminal type XVIC
3. Under SETTINGS/VIC SETTINGS/ menu, ensure that HARDWARE SCALING is checked
4. start a graphically intensive game (i.e. the GORF cartridge or a shoot-em-up
game).
5. Press CTRL-D to engage full-screen mode.
6. CPU usage will be very high compared with HARDWARE SCALING unchecked.
