gnome-system-monitor resources graphs unstable on window resize with VESA

Thanks for your report, are you running compiz? does it happen without it? Which video card do you have? I cannot reproduce that behavior on my Hardy system.

I booted from the live CD. Compiz was installed by default. I de-installed compiz using symantic. The problem still happened.

Here are the details of my graphics card:

ubuntu@ubuntu:~$ sudo lspci -v -s 02:00.0
02:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 440 AGP 8x] (rev a2) (prog-if 00 [VGA controller])
 Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 12
 Memory at ec000000 (32-bit, non-prefetchable) [size=16M]
 Memory at e0000000 (32-bit, prefetchable) [size=128M]
 [virtual] Expansion ROM at ed000000 [disabled] [size=128K]
 Capabilities: [60] Power Management version 2
 Capabilities: [44] AGP version 3.0

It is a 4 or 5 year-old low-spec 3d card, but runs compiz graphics eye-candy in Gutsy (just). The card has a maximum memory of 64Mb. I am not sure how much is actually in the card though.

Also worth noting: when resizing causes the problems, the cpu climbs to 100%, and stays at 100% until I resize the window back to the default start size.

This may be related to bug #187383, "...That looks like slow cairo rendering and like and xorg or driver limitation". I can confirm that Xorg is using all the CPU. Changing the System Monitor resources update interval makes no difference, however.

I have tried the problem with the default driver, and with nvidia-glx installed. No difference.

Where do I find Xorg.0.log ?

Same problem.

Monitors screens become black when the size is too high and the CPU is 100% charged.

I don't have compiz and my graphics card is:
 VGA compatible controller: nVidia Corporation G70 [GeForce 7300 GT] (rev a1) (prog-if 00 [VGA controller])
(with the last nvidia driver downloaded from their website)

gnome-system-monitor 2.21.5-0ubuntu1
Ubuntu hardy (development branch) - Alpha 5

Hello,

I have the same problem today, since the software upgrade.

I use:
gnome-system-monitor 2.21.5-0ubuntu1
Ubuntu hardy (development branch) - Alpha 5

Yesterday the background was white and it was OK.
Now, it is black and the graphs are blury.

I am seeing this problem now on a fresh fully updated install of 8.08-beta i386 desktop running in the current virtualbox which uses the vesa video driver.

Virtualbox is allocated 500megs of system memory on my twin xeon intel se7505vb2 server with 4gigs of ram and with an ATI 9800 Pro graphics card (all of which probably is not important)

The screen graphic is not drawn to the correct width of the black background that is drawn for it to occupy.

See attached screenshot.

Having looked at a previous screen shot the problem I am seeing is probably different to what was originally reported and may need to be reported as a separate bug report.

I will wait a day or so and check this bug regularly before doing so.

I have similar problems with hardy beta (Live CD, no install)

ubuntu@ubuntu:~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=8.04
DISTRIB_CODENAME=hardy
DISTRIB_DESCRIPTION="Ubuntu hardy (development branch)"

besides that the graph is not properly scaled the whole live system seems to stall/being occupied by the system monitor. The load on 1 off my 2 CPUs goes up to 100% according to the monitor.

the text on the graph axis is not readable. similar to https://bugs.launchpad.net/ubuntu/+source/gnome-system-monitor/+bug/68620

Installing nvidia-glx has fixed this for me.

I display the resources tab of system monitor, showing the 3 History graphs.

When I then resize the window (increasing the size), beyond about 600 pixels in height or beyond about 700 pixels width, the graph backgrounds and scales turn negative, and graph refresh fails to consistently redraw over previously displayed lines. The graph line thickens.

When I maximise the system monitor window (screen size is 1620x1050), system monitor displays the same behavior, but also the application freezes - failing to respond to mouse-clicks - changing tabs, etc . When I close the window the system monitor closes successfully.

I HAD the same problem on a newly installed hardy heron. This is what fixed it:

Went to appearance preferences, visual effects, chose normal. Nvidia-glx started to install. After it did, this bug was gone.

this seems to be still a problem. running live image session (http://cdimages.ubuntu.com/daily-live/20080408/ at that time) with free NV driver

cant reproduce on the hardy RC live cd with the nv driver, where i have previously had problems in older builds

I was not using the live cd, hardy was installed, booted from the hard drive. I have no problems now.

what videocard and driver do you have?

Videocard: Nvidia Geforce4 Ti 4800. How do I tell what driver I have?

looking at bug #187383 there is a new version of the gnome-system-monitor in hardy-proposed, which may fix this bug.

can anyone update to the proposed package, to see if this bug is still present?

I've installed gnome-system-monitor_2.22.1-0ubuntu2_i386.deb and here it still looks exactly like on

http://launchpadlibrarian.net/12808034/Screenshot.png

it uses less CPU, but still more than in 7.10 and it still has this "shrinked window to 3/4 of the real width" look.

@david bentley and ianst, that looks like a seperate bug. help ubuntu and make a bug report about it :)

anyone experience the type of graphical error shown in the first screenshot still?

> ianst, that looks like a seperate bug. help ubuntu and make a bug report about it :)

I've did this two weeks ago but it was marked invalid and a duplicate of this one! What now?

https://bugs.launchpad.net/ubuntu/+source/gnome-system-monitor/+bug/224397

With the latest updates the state is the same please see the screenshots.

and another tab...

And here you can see that system monitor takes 8 percent of cpu to refresh processes page and 60 percent (!) when drawing graphs.

Of course the look of the whole window is fully wrong like the other tabs (previous screenshots).

As far as I understand the problem reported by David Bentley and me has better diagnosis in:

https://bugs.launchpad.net/ubuntu/+source/gnome-system-monitor/+bug/208570

Maybe this entry can be closed, if other issues are resolved?

Which video driver are you using? Vesa?

Yes I've taken this picture as I've used Vesa driver, and now using ATI I don't observe that effect:

Ok, thanks re assigning to vesa then. looks similar to bug 208570.

Hi Andrew,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

If by chance you can no longer reproduce the issue on Lucid or if you
feel it is no longer relevant, please mark the bug report 'Fix Released'
or 'Invalid' as appropriate, at the following URL:

  https://bugs.launchpad.net/ubuntu/+bug/194953

Sadly, I don't have the same hardware as when I first reported this defect, so can't confirm whether it sill occurs on lucid.
